The cross section for the~2C(p, pn)~~C reaction measured at 1.73 GeV is 28.2+3.6 mb, a value virtually identical with that of the corresponding proton-induced reaction (27.5 + 0.6 mb) .The C(w, 7f n)~C and 9F(x" 7(. n)1sF cross sections at 2.36 GeV are 19. 4+1.5 and 16.0 +2.0 mb, respectively. Each is about 25/o lower than the corresponding reaction induced by 2.4-GeV protons. These results are discussed in terms of the free-particle cross sections.
