Charged pion production induced by 201 MeV protons on Ni58 and Ni64 has been studied. The double differential cross sections have been measured over a wide angular range. Different behavior of the angular distribution is observed for low and high energy pions. The yield of positive pions shows a pronounced forward peaked component. The deduced total production yields are about the same for (p,π+) on both isotopes whereas that for (p64,π−) is twice as large as for (p58,π−).
