QUADRUPOLE-QUADRUPOLE PLUS PAIRING INTERACTION APPLICATION TO TRANSITION CHARGE-DENSITY CALCULATIONS IN SOME EVEN-EVEN PALLADIUM NUCLEI

Here we report the microscopic variational model calculations for the recently available experimental data on transition charge densities (TCD) of Pd104,106,108,110 nuclei employing quadrupole-quadrupole plus pairing interactions operating in the 2p1/2, 1g9/2, 2d5/2, 3s1/2, 2d3/2, 1g7/2, and 1h11/2 valence spaces. Results for different p-n interaction strengths are also given. It is seen that TCD, being sensitive to the strength parameters, can act as one of the best means for the fixing of these parameters accurately. The results of TCD, for quadrupole excitations, using the p-n interaction strength parameter =-0.0231 MeV b-4, are in excellent agreement. The calculated static properties from the Hartree-Fock-Bogoliubov (HFB) model, employed for TCD calculations, are also in good agreement. Deviation in the TCD results for hexadecupole transitions, points toward the need for some modifications so as to simulate the other interaction effects. © 1994 The American Physical Society.
