Proton decay spectroscopy of S-28 and Cl-30

States in S-28 and Cl-30 have been studied using one- and two-proton decay spectroscopies. In the first spectrometer setting, states in( 28)S were populated following one-neutron knockout from a fast S-29 beam. Three new states are observed in S-28 from one- and two-proton decays. For the two-proton case the nature of the decay was investigated and found to proceed via sequential two-proton emission. For the second setting, states in Cl-30 were populated via one-proton knockout from a fast Ar-31 beam. The decay energy of the ground and first excited state were measured with the ground-state decay energy found to be in disagreement with a previous measurement. The spin and parity of these two Cl-30 states were inferred from shell-model calculations.
