This is a proposal to study p-p elastic scattering at the highest possible P{sub {perpendicular}}{sup 2} at NAL, using a CH{sub 2} or H{sub 2} target placed directly in the extracted beam and a double arm spectrometer. We expect to be able to set an upper limit at the level d{sigma}/dt/d{sigma}/dt{sub t=0} {approx} 10{sup -14}. This would be sufficient to determine if there are exactly three regions in the p-p interaction with considerable precision.

We will study the reaction {bar p}n {yields} {bar p}p{sup {paragraph}-} at 20, 40, and 60 GeV/c in a bubble chamber experiment using a sample of 1,000,000 pictures.

The authors have measured the asymmetry in the cross section for the reaction {gamma}p {yields} {pi}{sup +}n between the two stages of polarization of the initial proton normal to the plane of scattering. The initial laboratory photon energies, k, were 5 GeV and 16 GeV, and the regions of momentum transfer, t, covered were 0.14 {le} {radical}-t {le} 1.01 GeV/c and 0.14 {le} {radical}-t {le} 0.78 GeV/c respectively. A butanol polarized target was used with the SLAC 20 GeV/c magnetic spectrometer. The data show a sizeable asymmetry at both 5 GeV and 16 GeV. The 16 GeV data peak at {radical}-t {approx} 0.30 GeV/c with an asymmetry of about -0.70, and the 5 GeV data pak at {radical}-t {approx} 0.80 GeV/c with an asymmetry of about -0.70. The direction of our normal to the scattering plane is along (photon in) x (pion out).

It is proposed to extend to the NAL energy range the investigation of elastic ''diffraction'' scattering and precision measurements of the total cross sections performed at BNL during the past decade. It is expected that this investigation will be of considerable interest and importance in regard to understanding the asymptotic behavior of forward and near forward scattering amplitudes. The investigation will be composed of two highly complementary parts, which in common utilize the same beam, most of the same equipment, and the same experimental area region. As our past experience has demonstrated, a knowledge of both the elastic ''diffraction'' scattering and the total cross sections to high precision is necessary to allow a meaningful theoretical analysis of either.

BNWL-1407 summarizes information gained from the Chemical Analyses of Sodium Systems Program pursued by Battelle- Northwest over the period from July 1967 through June 1969. Tasks included feasibility studies for performing coulometric titration and polarographic determinations of oxygen in sodium, and the development of new separation techniques for sodium impurities and their subsequent analyses. The program was terminated ahead of schedule so firm conclusions were not obtained in all areas of the work. At least 40 coulometric titrations were carried out and special test cells were developed for coulometric application. Data indicated that polarographic measurements are theoretically feasible, but practical application of the method was not verified. An emission spectrographic procedure for trace metal impurities was developed and published. Trace metal analysis by a neutron activation technique was shown to be feasible; key to the success of the activation technique was the application of a new ion exchange resin which provided a sodium separation factor of 10{sup 11}. Preliminary studies on direct scavenging of trace metals produced no conclusive results.

The authors propose a survey experiment for a neutral hyperon beam, to measure production of {Lambda}{sup 0}, {bar {Lambda}}{sup 0}, {Xi}{sup 0}, {bar {Xi}}{sup 0}, K{sub 1}{sup 0} - K{sub 2}{sup 0} near zero mrad. by 200 GeV protons on complex nuclei. The detector will be sensitive to polarization of the hyperons. The same apparatus will then be used to search for {Xi}{sup 0} {yields} p{pi}{sup -} and to measure {Lambda}{sup 0} and {bar {Lambda}}{sup 0} total and diffractive elastic cross sections in hydrogen.
