  The experiment of determination of the 64Zn(n,a)61Ni reaction cross section
in the 5.0-6.75 MeV neutron energy range was performed at the 4.5 MV Van de
Graaf accelerator at the Institute of Heavy Ion Physics, Peking University,
Beijing. Double section ionization chamber with grid was used for direct
registration of the reaction products. The cross sections and angular
distributions were extracted from the experimental data. The obtained values
were compared with the results of other authors and theoretical estimations.
The analysis of the experimental data and model calculations were carried out.
