Previous work on generalizations of the ABFST multiperipheral model is extended to allow for vector meson exchange. The intercept of the Pomeranchon pole, the magnitude of asymptotic total cross sections and off-shell corrections to them are calculated.

The elements of the environment relating to transportation and handling include temperature, solar radiation, precipitation, humidity, pressure, shock, and vibration. While each of these deserves consideration, the latter two, shock and vibration, are perhaps the least understood. The report discusses all of these elements, but concentrates largely on shock and vibration. Emphasis is upon the necessity of understanding both the product and the environment. To that end, descriptions of the environment which have been derived statistically are discussed. Land, sea, and air transport are considered. Current knowledge of the handling environment is indicated.

The theory of coherent transverse oscillations of two particle species is extended to include strong species-species and image forces. It is shown that in general the species-species force can considerably alter the instability threshold. Conversely, it is shown that the limit on the performance of an electron ring accelerator imposed by the requirement of stable ion electron oscillations, is not significantly improved by the inclusion of images.

From Battelle colloquium on defects in oxides; Columbus, Ohio, USA (17 Sep 1973). The accumulation of concentrated defects in /sup 238/PuO/sub 2/ by selfradiation damage is shown to proceed by a simple exponential function for samples which are initially defect free. Anomalous behavior for both ingrowth and damage recovery is related to helium inventory, but not to uranium, which is the daughter product of the alpha decay. The annealing of samples having achieved a saturation of defects at 25 deg C proceeds through a two-stage mechanism, the first having an activation energy of 0.17 eV. Both defect production and annealing behavior are characterizBd by x-ray diffraction and electrical conductivity measurements for 25 deg C < T < 1000 deg C. (auth)

From symposium on noble gases; Las Vegas, Nevada, USA (24 Sep 1973). A method was developed for the analysis of air and natural gas samples containing trace amounts of noble gases. The gas samples are preconcentrated by reaction with calcium at 900 to 1000 deg C and analyzed by mass spectrometry on an automated instrument. Methods of relating the concentrated sample to the original sample and the preparation of gas standards are given. The accuracy of the technique at the 25 ppM level was determined. The precision of the method and requirements for improving the technique are also discussed. (auth)

From American Chemical Society 2nd joint conference on sensing of environmental pollutants; Washington, District of Columbia, USA (10 Dec 1973). Commercially available 20 cfm cascade impactors were evaluated under field sampling conditions for particle sampling bias caused by interstage losses and by non-wind direction sampler oriertation. An integrated sampler using an impactor and a winddirection self-orienting cowl attachment decreased particle sampling bias. (auth)

From 3rd international conference on atomic collisions in solids; Gatlinburg, Tennessee, USA (23 Sep 1973). X-ray spectral measurements of S, Cl, and Ar atoms moving in solid carbon targets are used to extract the equilibrium distribution of vacancies in the valence and L-shells of the projectiles. It is found that the state of excitation is much higher than the mean charge measured after the projectile has left the solid. A simple model is used to deduce the expected final charge state distribution, and these are compared to thin foil measurements. The results support the Betz-Grodzins model for ions moving in solids.

From international symposium on electron and photon interactions at high energies; Bonn, F. R. Germany (27 Aug 1973). The review of light cone physics covers various aspects which are physically interesting, evaluation of the importance of the ideas which foim the nucleus of light cone physics, understanding of the limitations and an analysis of possible ways to overcome the difficulties of light cone physics.

From 2nd international conference on elementary particles; Aixen- Provence, France (6 Sep 1973). Measurements of the polarization parameter for the reaction pi /sup -/p yields pi /sup o/n were made at the five momenta 1.03, 1.245, 1.44, 1.5 and 1.79 GeV/c. A polarized target was used, with polarizations achieved ranging from 48 to 57%. Salient features of the experiment were the use of neutron counters for time-of-flight measurements as well as angular information and the use of optical spark chambers, seven to eight radiation lengths thick, for the detection of the gamma rays from the decay of the pi /sup o/. The center-ofmass angular range covered by the 20 neutron counters was typically --.78 < cos THETA /sub c.m. <.87. For each momentum there are approximately 10,000 events which fit pi /sup -/p yields pi /sup o/ n with a confide nce level of at least 10%. (auth)

The technical bases of the emerging technology of nuclear stimulation of natural gas fields, the potential of this method for increasing the gas supply of the US, and public issues related to this technology are discussed. A technical appendix is provided with information on: reservoir producing characteristics; explosive design, availability, and cost; firing and space of explosives; economic parameters; and tabulated statistics on past and current projects on nuclear stimulation.

From eleventh international annual meeting of the German Society of Nuclear Medicine; Athens, Greece (24 Sep 1973). Progress in quantitating the distribution of isotope within organs on sequential images of the whole body using the whole-body scanner, and on techniques of reconstructing the three- dimensional distribution from multiple gamma-camera views using a variety of different algorithms is reported. The following variables are involved in the precise quantitation of the amount of radiopharmaceuticals in regions of the body: geometry effect, patient thickness, thickness and homogeneity of isotope distribution, source position, one photon attenuation coefficient. The whole- body scanner used consists of 64 detectors distributed as four rows of 16 detectors with a diagonal offset to give good resolution and adequate collimation between the single 3.2-cm diameter by 3.8-cm thick sodium iodide (TI) crystals. The patient is positioned on a bed that is moved over the detector array and pulse-height selection is used to separate pulses between different isotopes. The scan durations can vary from 0.75 minute to hours. (auth)

From 11th international annual meeting of the German Society of Nuclear Medicine; Athens, Greece (24 Sep 1973). Rubidium-81 is a new myocardial imaging agent with an ideal T/sub 1/2 of 4.6 hr and energies acceptable for gamma-camera viewing. The target-to-nontarget ratio for heart image to background in the projection images is usually less than 2: 1, thus good statistics are necessary to delineate lesions. The low radiation dose and availability of this isotope allow one to obtain 6 to 10 times the data, and /sup 81/Rb is probably superior to /sup 129/Cs and /sup 43/K for myoca rdial imaging if adequate collimation is present.
