Study of the germanium isotopes with the (p,t) reaction

The levels of ^{70, 71, 72, 74}Ge have been investigated with the (p, t) reaction at 20 MeV. Strong transitions to the ground state and to the 2₁⁺ and 3₁^? collective levels were observed for all even isotopes. A comparison of the experimental angular distributions with those calculated assuming a closed ⁷⁰Ge core indicates that only ≈ 15% of the observed ground state L = 0 transition strength comes from $\text{(1}\text{g}{}_{\mathrm{<mtext>9</mtext><mtext>2</mtext>}}\text{)}{}^2\text{and}\text{(2}\text{p}{}_{\mathrm{<mtext>1</mtext><mtext>2</mtext>}}\text{)}{}^2$ pick up. The excitation energies and L-transfers obtained in the present work are found to be in generally good agreement with previous data.
