Nuclear reactions of nickel with protons up to 56 MEV

Abstract Excitation functions have been measured for a number of nuclear reactions of nickel isotopes with 5–56 MeV protons. The following peak cross-sections were determined: 58 Ni-( p , pn )-260 mb, ( p , p 2 n )-21 mb, ( p ,2 p )-540 mb, ( p ,2 pn )-350 mb, p , α )-40 mb, ( p ,2 p 2 n )-63 mb, ( p , αpn )-38 mb; 60 Ni-( p , n )-320 mb, ( p ,2 pn )-180 mb, ( p ,2 p 2 n )-200 mb, ( p , αn )-72 mb, ( p , α 2 n )-14 mb; 61 Ni-( p , n )-480 mb; 62 Ni-( p , n )-480 mb; 64 Ni( p , n )-670 mb. Cross-sections for the following reactions were determined up to E p = 56 MeV: 58 Ni-( p , αp 2 n ), ( p , α 2 pn ); 60 Ni-( p , p 3 n ), ( p , α ), ( p ,2 p 3 n ), ( p , α 2 pn ); 61 Ni-( p , α ). Measurements were also made for the cross-sections of 60 Co formation from natural nickel.
