Vibrational Spectrum ofCd114

The energies and angular distributions of proton groups produced in the ${\mathrm{Cd}}^{113}(d, p){\mathrm{Cd}}^{114}$ reaction were measured with an over-all resolution of 12 keV. A distorted-wave analysis, employing experimentally determined optical-model parameters, was used to extract values of $l_n$ and spectroscopic strengths for states up to 3.8-MeV excitation in ${\mathrm{Cd}}^{114}$. The spectroscopic factors of the low-energy states are compared with those predicted by a microscopic theory of nuclear vibrations. Reasonable agreement is found for the ground and one-quadrupole-phonon states, but not for the two-phonon states.
