Theoretical Study of Isoscalar Giant Monopole Resonance in 110,112,114,116Cd Isotopes Using Self-consistent Skyrme HF-BCS and QRPA
摘要
In this work, the isoscalar giant monopole resonance (ISGMR) of even-A Cadmium (110,112,114,116Cd) isotopes has been studied in the framework of self-consistent Skyrme Hartree–Fock–Bardeen, Cooper and Schrieffer (HF–BCS) and quasiparticle random phase approximation (QRPA). Ten Skyrme-type parameters are used in the calculations, i.e., SkP, eMSL09, MSL0, T44, BSK20, Ska, SV, QMC2, SII and SGOI having different values of the nuclear matter incompressibility modulus KMN. The calculated strength distributions, centroid energy Ecen, constrained energy Econ, and scaling energy Es of ISGMR are compared with available experimental data. It has found that the interactions with low incompressibility value more suitable to describe the ISGMR strength distributions for all isotopes, where the high KNM shift the peak to upper energy and low strength while the low KNM shift it to less energy and upper strength.
