The excited states of 71Ge have been investigated via the 71Ga (P, n71Ge reaction with the proton beam energies from 2.5 to 4.3 MeV. The parameters of the nuclear level density formula have been determined from the extensive and complete level scheme for 71Ge. The Bethe formula for the back-shifted Fermi gas model and the constant temperature model are compared with the experimental level densities.


Key words: Level schemes of 71Ge, 71Ga (P, n71Ge reaction, angular distribution, Fermi gas model.
