Abstract
Cross sections at six angles from 0° out to 20° in the c.m. system have been measured for the → transition in the reaction at MeV. The 0° cross section is in good agreement with measurements of the same quantity on at similar energies. The 0° () cross section gives a value of 161 ± 17 MeV for the volume integral of the central part of the spin-isospin interaction; a theoretical value of 161 MeV is in good agreement. A distorted wave calculation for a pure, Gamow-Teller transition is in fair agreement with the measured () angular distribution. An approximate resolution of the weak → transition to the first excited state of at 1.8 MeV shows an angular distribution of a very different character corresponding to a transition of mixed angular momenta.
