Abstract
This project aimed to investigate proton unbound states in 32Cl
using the 32S(3He; t) charge-exchange reaction. This research is
relevant both in the context of nuclear structure and astrophysics.
Excited states in 32Cl up to Ex 6 MeV were produced using a
50 MeV 3He++ beam from the K200 separated sector cyclotron
at iThemba LABS. The triton ejectiles were mass analysed and
detected at the focal plane of the K600 magnetic spectrometer.
An additional segmented silicon detector array called CAKE was
used to detect the unbound protons from states in 32Cl in conjunction
with the tritons. In this work we looked for potential
sources of isospin admixture that could explain the apparent violation
of the Isobaric Multiplet Mass Equation (IMME) for the
A = 32, T = 2 quintet. We also investigated the possibility of determining
the 31S(p;
) reaction rate indirectly, via measurements
of the partial proton widths of unbound states in 32Cl.
