An experiment was performed to extend the knowledge of excited states in neutron-deficient Ca isotopes. In particular, the first excited state in 36Ca was searched for to obtain information on the isospin dependence of the nucleon-nucleon interaction near the proton drip line from a comparison with its stable mirror nucleus, 36S. The 36Ca ions were produced using a two-step fragmentation technique with a 37Ca secondary beam, and in-beam γ-rays were measured. First results are the energy of the first 2+ state in 36Ca, E(2+)=3036(11) keV, and the cross section for the reaction 37Ca → 36Ca at 61.A MeV. In addition, the de-excitaion of the first 2+ state in 28S has been observed.
