In order to extend our knowledge of the weak spreading width to the nuclear mass 30 region, parity-violation measurements have begun at the Triangle Universities Nuclear Laboratory using the {sup 31}P(p,{alpha}{sub 0}){sup 28}Si reaction. Longitudinally polarized protons are scattered from {sup 31}P nuclei at several MeV, and a large solid angle silicon-strip detector detects the alpha particles at backward angles. By rapidly reversing the spin direction of the protons, we measure the helicity dependence of the alpha yield. A discussion of the working system and preliminary results are given. {copyright} {ital 1999 American Institute of Physics.}
