TITLE=/Excitation function measurements of 40Ar(p,3n)38K,
40Ar(p,2pn)38Cl and 40Ar(p,2p)39Cl reactions/;
PURPOSE=/For the production of 38K, excitation functions of the
40Ar(p,3n)38K reaction and its accompanying reactions
40Ar(p,2pn)38Cl, and 40Ar(p,2p)39Cl were measured at the
proton energy of 20.5 - 39.5 MeV to determine the optimum
conditions of irradiation./;
