Levels ofGe68excited by the (p, t) reaction

The ${}_{}{}^{70}{}_{}{}^{}\mathrm{Ge}(p, t){}_{}{}^{68}{}_{}{}^{}\mathrm{Ge}$ reaction has been studied at 26 MeV incident energy with an overall resolution of 10 keV using a split-pole spectrometer. Forty-one ${}_{}{}^{68}{}_{}{}^{}\mathrm{Ge}$ levels, among which twenty-eight are observed for the first time, are populated below 5.2 MeV excitation energy. Angular distributions are obtained, and comparison with distorted-wave Born approximation calculations allows spin and parity assignments. An interesting result is the discovery of the first excited $0^{+}$ level at 1.753 MeV as well as seven other $0^{+}$ levels above 2 MeV energy. Five $J^{\pi }=2^{+}$ and four $J^{\pi }=4^{+}$ levels are observed for the first time. We also establish the position of the first $J^{\pi }=3^{-}$ level at 2.651 MeV and the possibility of a $J^{\pi }=6^{+}$ level at 4.456 MeV excitation energy.
