• Energy spectra and angular distributions were measured for protons emitted from Zn^<64> and Zn^<66> bombarded with 141.1MeV neutrons. Any of level density formulae fits equally well the energy spectrum for backward angles. The constant temperature formula gives 1.22±0.07MeV and 1.35±0.05MeV as the nuclear temperatures of Cu^<64> and Cu^<66> respectively. Using the Lang level density formula, the level density parameters for Cu^<64> and Cu^<66> are given as 8.26±0.78MeV^<-1> and 5.39±0.56MeV^<-1> respectively. The proton angular distributions are concave and symmetric around 90°. Anisotropy is greater for higher energy protons. The anisotropy of lower-energy protons emitted through the (n, p) reaction is found to be comparable to the anisotropy of those emitted through the (n, np) reaction. The cross sections for the (n, p) and (n, np) reactions for Zn^<64> through compound process are 127±9mb and 169±26mb and those for Zn^<66> 30.3±1.1mb and 40.5±8.3mb respectively. The direct (n, p) reaction for Zn^<64> has a cross section of about 5mb.
