Determination of Proton Binding Energies for 89Y, 90Zr, 91Nb and 93Tc from (p,,γ) Reaction Q-Values
In the course of spectroscopic work with (p,r) reactions in the A = 90 mass region, we had found discrepancies between the reaction Q-values, i.e., the proton binding energies, derived from our measurements and those given in the 1964 mass table /1/ and also in the 1971 mass table /2/. Therefore, we made a systematic investigation in order to obtain more accurate values. The reactions studied were 88Sr(p,r)89Y, 89Y(P,r)90Zr, 9OZr(p,r)91Nb and 92Mo(p,r)93Tc.
