Abstract
States in and have been studied using one- and two-proton decay spectroscopies. In the first spectrometer setting, states in were populated following one-neutron knockout from a fast beam. Three new states are observed in 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 were populated via one-proton knockout from a fast 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 states were inferred from shell-model calculations.
