studies performed in the frame of a project destined for the search of new
(t,n) and (p,n) reactions of interest in nuclear reactors are described.
Experimental evidences of the observations of the reactions: 46Ti(t,n)48V, 48Ti(p,n)48V, 52Cr(t,n)54Mn, 56Fe(p,n)56Co, 72Ge(t,n)74As and 74Ge(p,n)74As,
are presented. Additional data on some secondary reactions, already
characterised for the production of 7Be, 56Co, 58Co, 65Zn and
