论文摘要
等效巨型单极共振（ISGMR）和等构巨型四极杆共振（ISGQR）的最新RCNP $（α，α'）$数据在$^{92,94,94,94,96,98,100} $中，在$^{92,94,94,96,98,100} $中，在一个完全自我互动阶段中分析了Quasipipipiper近似（ncrp）。其中考虑了配对相关性和可能的轴向变形。 Skyrme使用了探索多种核物质性能的Skm*，Sly6，Svy6，Svbas和Skp $^δ$。我们讨论了单极强度ISGMR的线形与ISGMR和ISGQR的$ K = 0 $分支之间的变形诱导的耦合之间的连接。 ISGMR Centroid Energy最好由力量SKP $^δ$描述，具有低压缩性$ k _ {\ infty} $ = 202 meV。 ISGQR数据通过SVBA更好地复制，该svbas具有较大的等值质量$ m^*/m $ = 0.9。需要同时描述ISGMR和ISGQR数据，并需要合适的值为$ k_ \ infty $和$ m^*/m $。还设想了QRPA处理软系统的可能扩展。
The recent RCNP $(α, α')$ data on the Isoscalar Giant Monopole Resonance (ISGMR) and Isoscalar Giant Quadrupole Resonance (ISGQR) in $^{92,94,96,98,100}$Mo are analyzed within a fully self-consistent Quasiparticle Random Phase Approximation (QRPA) approach with Skyrme interactions, in which pairing correlations and possible axial deformations are taken into account. The Skyrme sets SkM*, SLy6, SVbas and SkP$^δ$, that explore a diversity of nuclear matter properties, are used. We discuss the connection between the line shape of the monopole strength ISGMR and the deformation-induced coupling between the ISGMR and the $K=0$ branch of the ISGQR. The ISGMR centroid energy is best described by the force SkP$^δ$, having a low incompressibility $K_{\infty}$ = 202 MeV. The ISGQR data are better reproduced by SVbas, that has large isoscalar effective mass $m^*/m$ = 0.9. The need of describing simultaneously the ISGMR and ISGQR data is stressed, with the requirement of suitable values of $K_\infty$ and $m^*/m$. Possible extensions of the QRPA to deal with soft systems are also envisaged.
