Continuum Structure of ${\mathrm{Ca}}^{40}$

The total $S^{1-}$ matrix of ${\mathrm{Ca}}^{40}$ has been calculated for excitation energies between 11 and 28 MeV. As typical results, the ($\gamma$, $p_0$) and the total absorption cross sections are shown and compared with experiments. It is shown that the proper treatment of the one-particle, one-hole shell-model continuum accounts for most of the observed structures.
