Abstract

An effective nucleon-nucleon spin-orbit force is included in a single-channel resonating-group calculation for the $^{3}\mathrm{He}$($^{3}\mathrm{H}$)+$\ensuremath{\alpha}$ system up to a c.m. energy of 113.1 MeV. The parameters of the spin-orbit force were chosen to reproduce the phase shifts for $p+\ensuremath{\alpha}$ scattering at low energies and the bound-state properties of $^{7}\mathrm{Li}$ and $^{7}\mathrm{Be}$. A phenomenological, parity-dependent imaginary potential is used to account for reaction channels. The calculation gives a reasonable account of the experimental differential cross sections and analyzing powers available in this energy region.NUCLEAR REACTIONS $^{3}\mathrm{He}$($^{3}\mathrm{H}$)+$\ensuremath{\alpha}$, bound states to 113.1 MeV (c.m.); calculated elastic differential cross sections and analyzing powers; resonating-group method.
