THE STRUCTURE OF S-32 .1. SPECTROSCOPY OF HIGHLY-EXCITED STATES

Assignments of I, pi, T are made to 30 levels in S-32 between 7.35 and 11.76 MeV excitation energy, making the spectroscopy of the T = 0 sta tes rather complete up to 10 MeV and that of the T = 1 states up to 12 MeV. A reassessment of existing data in the light of the new results clarifies the spectrum of I-pi = 1(+), T = 1 states up to 15 MeV excit ation energy. High-spin states (I = 5-7) below 10 MeV excitation energ y have been investigated by n-gamma angular-correlation measurements w ith the Si-29(alpha, n gamma) reaction at E(alpha) = 14.4 MeV. Five g- wave resonances of the P-31(p, gamma) reaction, leading to the formati on of I-pi = 4(+), 5+ states in S-32, have been identified between 10 and 12 MeV excitation energy. The spectrum of T = 1 states between 10. 7 and 12 MeV, has been investigated by measurements of gamma-ray angul ar distributions on resonances of the P-31(p, gamma) reaction and by m easurements of resonance strengths. Several S-32 levels between 7.35 a nd 8.75 MeV excitation energy were studied as final states in resonanc e decays. Finally a search was performed for I-pi = 0(+) resonances of the Si-28(alpha, gamma) reaction.
