An experiment was performed to study excited states in neutron-deficient nuclei around Ca. After a first fragmentation of the primary beam, the one-neutron knockout reaction was used to produce 36Ca ions from the 37Ca secondary beam and in-beam γ rays were measured. 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. 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. Furthermore, for two other Tz = -2 nuclei, 28S and 32Ar, the deexcitation of the first 2+ states has been observed.
