Processes of energy deposition by heavy particle impact. Technical report No. 2
Experimental studies of the Li/sup +/ + He interaction have been extended to smaller internuclear separations to clarify a discrepancy between experiment and theory in the elastic cross sections and to observe and measure cross sections for inelastic excitation. For R less than or equal to 0.5 a/sub 0/ the elastic scattering differential cross section is observed to droop far below that expected from a single-state interaction based on ab initio ground-state potentials. In this same region of R both one- and two-electron excitations of He are observed to be strongly excited, and cross sections were measured for each of them. The lowest inelastic channel is an electron-capture state, which is observed indirectly to be strongly populated also. A diabatic correlation diagram is constructed that exhibits the basic interactions responsible for the excitation.

Test and Evaluation of Alco/BLH Prototype Sodium-Heated Steam Generator: Final Report
A 30-Mwt prototype sodium-to-sodium intermediate heat exchanger and a 30-Mwt prototype sodium-heated steam generator were tested in combined operation in its Sodium Components Test Installation. This report contains the results of test and evaluation of the steam generator. During plant performance tests, performance degradation was observed, which resulted in the initiation of a diagnostic test series. This test series revealed that under certain operating conditions, the thermohydraulic characteristic of the steam generator changed either suddenly or gradually, resulting in overall performance degradation. A structural failure, requiring retirement of the unit, occurred before the diagnostic test series and analytical support effort were completed. This report describes the thermohydraulic and structural performance, including the structural failures, and related evaluation analyses of the Alco/BLH prototype steam generator performed prior to termination of the test and evaluation program. In addition, the report presents a post-test examination plan to obtain data that could possibly explain the cause of performance anomalies and structural failures experienced during testing.

Geothermal Resource Investigations: Imperial Valley, California. Site location report, deep geothermal test well
Data for use in siting a deep geothermal test well in the East Mesa area of Imperial County, California are summarized. The data relate to a geothermal anomaly known as the Mesa anomaly. It is concluded that the thermal feature forming the Mesa anomaly is a manifestation of a sizable convective hydrothermal system embracing an area of about 19 square miles and a considerable volume of saturated sediment in the Salton trough. The upper surface of the thermal feature between depths of 200 and 1,000 feet is irregular being shaped somewhat by ground-water movement. The area of greatest apparent heat flow is in SE/sup 1///sub 4/ of Sec. 6, T. 16 S., R. 17 E., and has a diameter of about /sup 1///sub 2/ mile. This area is an attractive drill site. The convective hydrothermal system regulating heat flow to the shallow subsurface is not known in detail but iso-resistivity maps suggest it exerts direct influence on near surface water temperature and salinity over an area of some 19 square miles. The mineral concentration of the ground water in this system will range from a minimum of about 3000 ppM to a probable maximum of about 30,000 ppM.

Liquid metal bearings technology for large, high-temperature, sodium rotating machinery. Development and test of high-temperature proximity probe for use in liquid sodium. Fourth topical report
An inductance-type, proximity-probe system for measurement of bearing film thicknesses and shaft orbits in high-temperature, liquid-sodium environment has been developed, built and tested. The probe system is designed to operate at temperatures up to 1200/sup 0/F and gap range of 0.004'' to 0.080'', with good linearity over about three-quarters of the range, when using probe pairs connected in push-pull. The probes were tested extensively in both gas and sodium environments, culminating in a 684 hours continuous test in a temperature range of 1050/sup 0/F to 1170/sup 0/F. The probes operated stably, repeatably and without undergoing performance changes.

SPECIFIC PROTONATION OF THE CARCINOGEN 7, 12-DIMETHYIBENZ [a]ANTHRACENE AND CHARGE LOCALIZATION IN THE a-COMPLEX
In the class of the polycondensed aromatic hydrocarbons, the concept of localized charge in a {sigma}-complex, e.g., the carbonium ion formed by addition of a proton or other electrophile to an aromatic ring, has so far received experimental evidence only in the case of anthracene. The ultraviolet spectrum of this compound in sulfuric acid is similar to that of the benzhydryl cation. Ph{sub c}C{sup +}Me. This result implies the protonation of anthracene at one meso-carbon atom and the localization of the positive charge at the other. The {sigma}-complex of the potent carcinogen 7,12-dimethylbenz[a]anthracene (DMBA) in acidic medium offers another example of this type of charge localization. The determination of structure was achieved by comparing the NMR spectra of DMBA in neutral and acidic solvents. The ratio of the integrated intensities of the proton peaks in the spectrum of DMBA is, from right to left, 3:3:5:1:1:2:1. The assignment of the 7-CH{sub 3} ({sigma}3.00) and 12-CH{sub 3} ({sigma}3.29) resonances was made by comparison with the spectra of 7-methylbenz[a]anthracene (7-CH{sub 3}, {sigma}3.03) and 12-methylbenz[a]anthracene (12-CH{sub 3}, {sigma}3.32) under the same conditions. A good general correlation exists between the methyl chemical shifts of the twelve monosubstituted methylbenzanthrancenes and the corresponding aryl protons of benzanthracene.

PHOTOCHEMICAL COUPLING OF BENZO [a]PYRENE WITH 1-METHYL-CYTOSINE;PHOTO-ENHANCEMENT OF CARCINOGENICITY
Irradiation of the carcinogenic benzo[a]pyrene (I) with 1-methylcytosine hydrochloride IIa (molar ratio 1:10) at 3500 {angstrom} in methanol-acetone produces the 6-(1-methylcytos-5-yl)-benzo[a]pyrene (III). The structure of the product shows the hydrocarbon bound through the most active 6-carbon atom to the nucleophilic 5-position of the base. In the second part, the possibility of observing carcinogenic effects on the mouse skin from non-carcinogenic hydrocarbons under the action of UV light is investigated. Both experiments provide evidence that the 4,5-double bond (K region) of I presumably does not play a role in triggering the cancer process.
