Reaction cross sections were measured from 10.4 up to 17.5 MeV for the
formation of Pu-236 and Pu-237 in the proton bombardment of Np-237. T
hick-target yield curves, based on the measured cross sections, were d
erived. The results are discussed and compared with literature data on
other reactions leading to the formation of Pu-236 and Pu-237 .
