Ionization energies for Rydberg ${}^4\mathrm{He}$ ($1snp{}^{1,3}P$) states using the correlated B-spline basis function method

Jing Chi, Hao Fang, Yong-Hui Zhang +2

We extend the correlated B-spline basis function (C-BSBF) method to high-precision calculations of the ionization energies of helium Rydberg $n^{1,3}P$ states ($n=24$--$35$). Using…
