Spectroscopy of neutron-deficient nuclei around 36Ca
A. Burger et al. (E. Clément, A. Gorgen, W.Korten, Ch. Theisen)
  An experiment was performed to extend the knowledge of excited states
  in neutron-deficient Ca isotopes.
  %%, and to search for the position of the proton drip-line at $Z=20$.
  %%
  In particular, excited states in \\up{36}Ca were searched for to
  %%% obtain information on the isospin-dependence of the
  %%% nucleon-nucleon-interaction near the drip-line from
  allow for a comparison with its stable mirror nucleus, \\up{36}S.
  %%
  Secondary beams of \\up{37}Ca and \\up{36}Ca were produced by
  fragmentation of a primary \\up{40}Ca beam with an energy of $95\\cdot
  A$\\,MeV on the SISSI target at GANIL.
  %%
  A variety of nuclei around \\up{36}Ca has been produced in a
  secondary Be target by neutron and proton-removal at beam energies
  around $61\\cdot A$\\,MeV.
  %%
  The produced nuclei were identified using the spectrometer {\\em
    SPEG}, and prompt $\\gamma$ rays were measured with the {\\em
    Ch\\^ateau de Cristal}.
  %%
  A preliminary value for the energy of the first $2^+$ state of
  \\up{36}Ca has been determined.
