Shell-Model States inCa49

The energy-level structure of ${\mathrm{Ca}}^{49}$ has been investigated by the deuteron-stripping reaction ${\mathrm{Ca}}^{48}(d, p){\mathrm{Ca}}^{49}$. Ten excited levels have been observed below 6.1 MeV, and the energies, angular momenta, and parities have been determined for most of the levels. The analysis of the angular distributions of the reaction protons permitted the identification of single-particle configurations at the following energies: $2p_{\frac{3}{2}}=0\mathrm{}$ MeV; $2p_{\frac{1}{2}}=2.028\mathrm{}$ MeV; $1f_{\frac{5}{2}}=3.95\mathrm{}$ MeV; $1g_{\frac{9}{2}}>~4.02$ MeV; and $2d_{\frac{5}{2}}>4.4\mathrm{}$ MeV.
