用全实加关联方法计算了类锂Ti19+离子1s23d~1s2nf(4≤n≤9)的跃迁能、振子强度及1s2nf(n≤9)态的精细结构劈裂.通过确定该Rydberg系列的量子数亏损,进而实现对任意高激发态(n≥10)的能量的可靠预言.将上述分立态振子强度与单通道量子亏损理论相结合,得到在电离阈附近束缚态间的跃迁振子强度与束缚态-连续态跃迁的振子强度密度,从而实现了Ti19+离子量子跃迁特性的全能域理论预言. 相似文献

The quantum pressure correction to the excitation spectrum of the trapped superfluid Fermi gases in a BEC-BCS crossover 下载免费PDF全文
Using quantum hydrodynamic approaches, we study the quantum pressure
correction to the collective excitation spectrum of the interacting
trapped superfluid Fermi gases in the BEC-BCS crossover. Based on a
phenomenological equation of state, we derive hydrodynamic equations
of the system in the whole BEC-BCS crossover regime. Beyond the
Thomas--Fermi approximation, expressions of the frequency
corrections of collective modes for both spherical and axial
symmetric traps excited in the BEC-BCS crossover are given
explicitly. The corrections of the eigenfrequencies due to the
quantum pressure and their dependence on the inverse interaction
strength, anisotropic parameter and particle numbers of the
condensate are discussed in detail. 相似文献
