NUCLEAR STRUCTURE STUDIES IN THE PALLADIUM ISOTOPES WITH (d,p) AND (d,t) REACTIONS
Many new energy levels are located in the odd-A palladium isotopes and the spin and parity values assigned. The parameters of the pairing theory, such as the single quasiparticle energies, the occupation numbers, the strength of the pairing interaction, etc., are evaluated. By means of them, the single-particle energies are obtained and compared with other nuclei of the same neutron shell. While the orbits 2d/sub 5/2/, 3s/sub 1/2/, and 2d/sub 3/2/, do not change their relati ve locations significantly, the 1g/sub 7/2/, orbit shows drastic changes. In the palladium isotopes the 1g/sub 7/2/ orbit is found to be below the 2d/sub 5/ 2/ orbit, while in zirconium it is as high as the 2d/sub 3/2/, orbit, and in tin somewhat above the 2d/sub 5/2/ orbit. This indicates that the interaction between the 1g/sub 7/2/ neutrons and the 1g/sub 9/2/ protons, which causes the shift of the lg/sub 7/2/ orbit, is most effective in palladium isotopes, i.e., where the lg/sub 9/2/ proton orbit is about half-full. The strength of the pairing interaction is evaluated to be GA = 29.2 plus or minus 0.9 Mev. (auth)
