Description
Beta-delayed proton radioactivity has been observed for the 28S isotope (Tz=-2), produced by projectile fragmentation of 85 MeV/u 36Ar. The measured half-life of 28S is 125±10 ms. Energy spectra of beta-delayed protons have been measured. The lowest T=2 state in the daughter nucleus 28P has been located at an excitation energy of 5900±21 keV. A comparison of the experimental data to the quadratic form of the isobaric multiplet mass equation shows that the energies of the five T=2 states of the A=28 quintet are well represented by that relation. Shell-model predictions for the half-life of 28S and the location and decay properties of the lowest T=2 state of 28P are in good agreement with experimental data. (orig.)
