Deuteron Stripping onCa46at 10-MeV Bombarding Energy

The reaction ${\mathrm{Ca}}^{46}\mathrm{}(d,p)\mathrm{}$ was examined at 10.129-MeV bombarding energy with an energy resolution of 15 keV. Absolute differential cross sections were measured at 24 scattering angles. The target was prepared by isotope separation to a relative purity in ${\mathrm{Ca}}^{46}$ of more than 99%. Twenty-eight levels in ${\mathrm{Ca}}^{47}$ up to 6.6-MeV excitation were identified. Twenty-one of the transitions could be analyzed by deuteron-stripping theory in the distorted-wave approximation to yield values of the orbital angular momentum of the transferred neutron and of the transition strength. Spin values are suggested for a number of ${\mathrm{Ca}}^{47}$ levels, partly based on the back-angle behavior of the $l_n=1\mathrm{}$ transitions and partly on shell-model systematics. The data are discussed in terms of shell-model sum rules and comparisons between the present data and other data on ${\mathrm{Ca}}^{47}$, as well as on other $N=27\mathrm{}$ nuclei, are presented.
