Abstract: | Cross sections have been measured for the elastic and inelastic scattering of electrons from 70Ge and 72Ge for momentum transfers from 0.65 to 1.14 fm?1. Values for the parameters of a Fermi type ground-state charge distribution were obtained from a phase shift analysis of the elastic cross sections. The rms charge radius corresponding to these parameters is 4.07±0.02 fm for 70Ge and 4.05±0.03 fm for 72Ge. Using DWBA analysis the reduced transition probabilities for the electroexcitation of the 21+ and 31? states were found to be: B(E2, ω)↑ = 19.7±1.2, 26.8±2.0 W.u.; B(E3, ω)↑ = 36±5, 37±7 W.u. for 70Ge and 72Ge respectively. The Jπ = 3? assignments for the state at 2.562 MeV in 70Ge and 2.515 MeV in 72Ge are confirmed. |
