⁷⁴Ge(t,p)⁷⁶Ge reaction

The reaction ⁷⁴Ge(t,p)⁷⁶Ge has been investigated with a 15 MeV triton beam. Twenty-six energy levels of ⁷⁶Ge were identified up to about 4 MeV excitation, five of which were unreported previously. Angular distributions were measured and compared with distorted-wave Born-approximation calculations. The first and second excited 0+ states in ⁷⁶Ge have been located at 1.911 and 2.901 MeV. Thirteen additional new spin and parity assignments have been made. The systematic structure of the low-lying 0+ states observed in the Ge(t,p) reactions on several isotopes support the idea of a shape transition previously proposed for these nuclei but for N ≥46 there is a rapid change toward a spherical shape.
