Lifetime Measurements In71geand a New Interacting Boson-Fermion Model Interpretation

The lifetimes of twelve low spin excited states have been measured in Ge-71 using the Doppler shift attenuation method in the Ga-71(p, n, y) reaction at 3.0 and 3.5 MeV incident energy. New interacting boson-fermion model calculations for this nucleus account well for the properties of all its levels known up to about 1.5 MeV excitation. [S0556-2813(99)03807-8].
