“…Furthermore for a sufficient number of particles the pairing model might become applicable. With the intention to present the data in a systematic way and to bring out the essential points, we will compare the experimental results with the simplest pairing model, following the review by Lane [9] and the original article by Kisslinger and Sarensen [10].…”

“…In the extreme limits of a uniform density function and a particle in the outer orbit assumed to have a precise radial position, a comparison of Eqs. (32) and (26) shows that the phase rule is obtained and that the angular distribution for the excitation of the 2+ state is approximately out of phase with the elastic scattering.…”

The differential cross sections for the excitation of the vibrational levels of nuclei are derived using the direct interaction between the projectile and the shell-model particles via a two-body force. The nuclear collective states are approximate solutions to the Hamiltonian consisting of a pairing plus a quadrupole interaction in a quasi-particle representation. The results obtained by this method are compared to those which follow from an interaction using collective coordinates for states of one and two phonons. Numerical results are given for the plane-wave first Born approximation scattering of alpha particles with a deltafunction interaction between the projectiles and the nuclear particle and for the plane-wave Born approximation scattering of electrons, assuming a Coulomb interaction.

“…Furthermore, the same deformation parameter (6=0.125) as used in [7] was assumed. The strength of the pairing interaction [31][32] for the calculation of quasiparticle energies and occupation parameters was estimated in such a way that it yields the gap parameter necessary to reproduce the odd-even mass difference.…”

The nuclear structures of 193Ir and 195Ir have been studied using the 194pt(t,~) and 196pt(t, c0 reactions. Levels up to ~2MeV in excitation energy were studied with a resolution of ~ 13 keV (FWHM) and spectroscopic strengths were extracted. The lowlying states in 193Ir have been interpreted in terms of both the Nilsson and the rotationvibration models including Coriolis, particle-vibration and rotation-vibrational coupl- . Surprisingly, there was no significant difference between the stripping and pick-up strengths for the low-lying states in 193Ir, suggesting that the equilibrium nuclear shape of 193Ir has large overlaps with the shapes of both 192Os and 194pt. The nuclear level structure of 195Ir appears to be similar to those of the lighter iridium isotopes.
