A Simple approach for precision calculation of Bethe logarithm
San-Jiang Yang, Jing Chi, Wan-Ping Zhou +4
In this article we propose a simple approach for the precision calculation of Bethe logarithm. The leading contributions are obtained using specific operators, while the remaining…
Angular part of trial wavefunction for solving helium Schrödinger equation
Sanjiang Yang
In this article, the form of basis set for solving helium Schrödinger equation is reinvestigated in perspective of geometry. With the help of theorem proved by Gu , we cons…
Application of the Hylleraas--spline basis set: Nonrelativistic Bethe logarithm of helium
San-Jiang Yang, Yong-Bo Tang, Yong-Hua Zhao +2
In this work, we report an application of Hylleraas--spline basis set to the nonrelativistic Bethe logarithm calculation of helium. The Bethe logarithm for , up to 1…
Relativistic full-configuration-interaction calculations of magic wavelengths for the transition of helium isotopes
Fang-Fei Wu, San-Jiang Yang, Yong-Hui Zhang +4
A large-scale full-configuration-interaction calculation based on Dirac-Coulomb-Breit (DCB) Hamiltonian is performed for the and states of helium. The operato…
An application of the Hylleraas-B-splines basis set: High accuracy calculations of the static dipole polarizabilities of helium
San-Jiang Yang, Xue-Song Mei, Ting-Yun Shi +1
The Hylleraas-B-splines basis set is introduced in this paper, which can be used to obtain the eigenvalues and eigenstates of helium-like system's Hamiltonian. Comparing with tradi…
