Experimental study of excitation functions for some reactions induced by deuterons (10-50 Mev) on natural Fe and Ti

Stacks containing high purity natural Fe and Ti foils were irradiated in de uteron beams with incident energies of 30 and 50 MeV. Reactions on Al foils were used for monitoring beam energy and intensity. The excitation functio ns up to 50 MeV for Ti-nat(d, x)Sc-44m,Sc-46,Sc-47,Sc-48, (nat)(Fe(d, X)Co- 55,Co-57, Mn-52,Mn-54, Cr-51 are presented and compared with the scarce lit erature values. No sharp peaks enabling clear identification of contributin g reactions on the different naturally occurring isotopes are present. Only for the reactions Fe-56(d, n)Co-57 (Q = -2.1 MeV), Fe-56(d, alpha or 2p2n) Mn-54 (Q values respectively 5.7 and -22.6 MeV), Ti-48(d, alpha or 2p2n)Sc- 46 (Q values 4 and -24.3 MeV) and Ti-48(d, 2pn)Sc-47 (Q = -13.7 MeV) on the major natural isotopes of Fe and Ti the cross sections reach values higher than 50 mb in the energy region studied.
