An experiment was performed to study excited states in neutron-deficient nuclei around Ca. A one-neutron knockout reaction was used to produce 36Ca ions from a 37Ca secondary beam, and in-beam
gamma-rays were measured. The 2+ energy in 36Ca is compared to the mirror nucleus 36S to deduce information on the isospin dependence of the nuclear force near the proton drip line. The energy of the first excited 2+ state in 36Ca and the cross section for the 1-neutron knock-out reaction from 37Ca at 45·A MeV were obtained. Furthermore, for two other Tz = −2 nuclei, 28S and 32Ar, the de-excitaion of the first 2+ state has been observed. |
