A total of 64 transitions were observed with an average precision of 2 keV in studying the gamma radiation from the 31P(n, γ)32P reaction using a Ge(Li) spectrometer. The neutron separation energy was measured to be 7 936 ± 1 keV. Comparison with (d, p) results indicates only a weak correlation between (n, γ) and (d, p) reduced widths. The reduced radiation widths follow a x2 distribution of ~2 degrees of freedom.

The decay of 1.3 h 87Kr, 2.8 h 88Kr, and 15 min 88Rb to levels in 87Rb, 88Rb, and 88Sr, respectively, has been investigated using high-resolution Ge(Li) detectors, a plastic beta-ray detector, and gamma–gamma as well as beta–gamma coincidence techniques. Isotope separation was achieved using gas-sweeping methods. Consistent level schemes have been constructed for each isotope under study.

A study of the gamma radiation following thermal neutron capture by natural silicon has been conducted. Precise energy measurements were obtained using a Ge(Li) counter and a decay scheme was constructed using the time correlation results obtained with a Ge(Li)–NaI(Tl) spectrometer. The neutron separation energy was found to be 8 474 ± 1 keV for 29Si. An examination of the reduced radiation widths revealed that, while E1 and E2 radiation agreed well with the single-particle estimate, the M1 strength was hindered by a factor of from 10 to 100.
