Decay scheme studies of short-lived isotopes of 69 ≦ A ≦ 88 produced by heavy-ion bombardment

Abstract

Sulfur-32 and 16O ion beams from the Rochester MP tandem Van de Graaff accelerator have been used to produce neutron deficient nucleides in the mass range 69 ≦ A ≦ 88. Halflives and energies ofγ-rays following decay of these isotopes were measured. Isotopic assignments were made by combining cross bombardment techniques with compound nucleus evaporation calculations. Many assignments could be made by measuring the half-lives and excitation functions for individual γ-rays formed with a variety of target-projectile combinations. Several activities were found for which the assignments are ambiguous, although several likely assignments are suggested.
