The ( Li, t) reaction was studied with a 34-MeV Li beam on enriched targets of "Mg, "Si, "Fe, 6Fe, and "Ni. The tritons were momentum analyzed in a quadrupole-dipole-dipole-dipole magnetic spectrograph and detected with a 1-m helical cathode proportional counter that covered about 4 MeV of excitation. Cross sections for the ( Li, t) reaction to strongly excited states are generally in the range of 1 to 10 It(,b/sr with exceptions up to 50 p,b/sr, Comparisons are made, where possible, between the selectivity of this reaction and other reactions leading to the same final nuclei, A similarity with single-neutron stripping is observed, which suggests a ( Li, t) reaction mechanism involving direct transfer of a proton-pair coupled to a single neutron. The possible two-step process { Li, d){d,t) is also suggested to account for two cases of f», hole states populated in the nickel isotopes. The "Ni( Li, t) 'Zn Q value was measured to be -4736+23 keV giving a mass excess of -56352+26 keV for 'Zn, This mass excess is believed to be more reliable than previous measurements with other techniques that differ by 500 keV. The triton spectrum for the 'SNi( Li, t} 'Zn reaction yields the first measurement of the energy levels of 'Zn, NUCLEAR HEACTrONS "Mg('Li, t~, 28Si('Li, t), "Fe('Li, t), '~re(6Li, t~, ¹(6I, i, t ), E(;L; --34 MeV; enriched targets, Q3D spectrograph, measured do/dQ, Et, energy levels~YSi,~'S,~7Ni, 5~Ii, 6'Zn; mass 6iZn; reaction mechanism discussed, correspondence with single-neutron transfer noted.
