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.

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
