Abstract：
Cross sections for (n,2n),(n,p) and (n,n′α) reactions have been measured on Gallium isotopes at the neutron energies of 13.5-14.6MeV using activation technique. The data of the cross sections are reported for the reactions of ⁶⁹Ga(n,2n)⁶⁸Ga,⁶⁹Ga(n,p)^69mZn,⁷¹Ga(n,p)^71mZn,and ⁷¹Ga(n,n′α)⁶⁷Cu. The cross sections of ⁶⁹Ga(n,2n)⁶⁸Ga reaction are 794±31,869±35 and 986±39mb at 13.5±0.2,14.1±0.1 and 14.6± 0.2MeV incident neutron energies, respectively. The cross sections of ⁷¹Ga(n,n′α)⁶⁷Cu reaction are given:1.3±0.1,1.7±0.1 and 2.5±0.1mb at 13.5±0.2, 14.1±0.1 and 14.6± 0.2MeV, respectively. The cross section of ⁶⁹Ga(n,p) 69mZn reaction is 21.5±1.0mb at 14.1±0.1MeV. The cross section of ⁷¹Ga(n,p) ⁷¹mZn reaction is 12.4±0.7mb at 14.1±0.1MeV. The neutron fluences are determined by the cross sections of ⁹³Nb(n,2n)^92mNb reaction.
