The lifetimes of twelve low spin excited states have been measured in ${}^{71}\mathrm{Ge}$ using the Doppler shift attenuation method in the ${}^{71}\mathrm{Ga}(p,n\gamma )$ 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.
