Positron polarization in a mirror transition
The positron polarization in the mirror transition N13, a predominantly Fermi transition, has been measured by detecting the circular polarization of the annihilation-in-flight quanta. The results indicate complete polarization of the positrons parallel to their momentum, showing that Fermi coupling contributes significantly to the positron polarization in the same sense as the Gamow-Teller coupling
Quasielastic axial-vector mass from experiments on neutrino-nucleus scattering
We analyze available experimental data on the total and differential
charged-current cross sections for quasielastic neutrino and antineutrino
scattering off nucleons, measured with a variety of nuclear targets in the
accelerator experiments at ANL, BNL, FNAL, CERN, and IHEP, dating from the end
of sixties to the present day. The data are used to adjust the poorly known
value of the axial-vector mass of the nucleon.Comment: 27 pages, 19 figures. Typos corrected; tables, figures and references

A proposal to measure polarization in pp, pi- p and pi+ p elastic scattering at 50, 100, and 150 GeV/c at the National Accelerator Laboratory
The authors propose to measure the polarization parameter in pp, {pi}{sup -}p, and {pi}{sup +}p scattering at incident momenta of 50, 100, and 150 GeV/c over the range 0.15 {le} -t {le} 1.5 (GeV/c){sup 2}. The apparatus consists of a polarized proton target, two spectrometer arms which determine the angles and momenta of both outgoing particles, and an on-line computer. The detectors are designed to operate at incident beam rates of up to 10{sup 8} beam particles/pulse. They anticipate an error in the polarization parameter P of .005 {le} {Delta}P {le} .01 over the range .15 {le} -t {le} .8 (GeV/c){sup 2} in 100 shifts of data taking and background studies
