Search for right-handed currents in the $\beta^{\pm}$ decay of $^{118}/Sb$

Abstract

We report on a recent experiment searching for right-handed currents in the /sup 118/Sb nuclear beta -decay. The correlation between the spin polarization and the beta -emission asymmetry of the positrons from the /sup 118/Sb decay is sensitive to the helicity structure of the weak interaction. A precision measurement of this correlation improves the limit on right-handed currents in beta -decay. (7 refs)
