Abstract

A large number of states up to approximately 3.3 MeV have been observed in the reaction 93Nb(d, p)94Nb utilizing magnetic analysis of the protons. A quintuplet of levels near the ground state is identified as the low-lying part of the configuration (πg 9 2)(νd 5 2)3. an interpretation of the data is made utilizing the recently established (p, n) residual interaction in 92Nb to calculate the low-lying levels of 94Nb. The energies of the observed levels and the intensities of the corresponding proton groups are well reproduced by the calculations.

In the pickup reactions 93Nb(d, t)92Nb and 93Nb(p, d)92Nb, the ground state configuration of 92Nb, (~zg~)(vd~.) gives rise to the six states 1, 2) of angular momentum and parity 2 +, 3 ÷, 4 ÷, 5 +, 6 + and 7 +. The relative cross sections can be interpreted 2) in terms of relatively small admixtures in the 93Nb ground state wave function of higher seniority states than the simple configuration (Trg0(vd~)ff=o . The question then naturally arises, can the (pn) residual interaction deduced from the pickup experiments successfully account for the energies and intensities of levels of the configuration (rcg~)(vd~) 3 produced in the stripping reaction 93Nb(d, p)94Nb? With this purpose in mind, this nuclear reaction has been studied on the Florida State University Tandem Van de Graaff. Simultaneously, three different groups have attacked the theoretical problem. In view of the similarity of the theoretical approach, their t This work was supported in part by the U.S. Atomic Energy Commission, contract number AT-(40-1)-2434; the U.S. Air Force Office of Scientific Research, contract AF-AFOSR-(2-432); the Nuclear Programme of the State of Florida; and the U.S. Atomic Energy Commission under contract with the Union Carbide Corporation.
