Fang Shuai-Shuai†, Hao-Xue Qiao
       
(a) The 11S0–21P1 oscillator strengths of confined helium with changing depth of outer confining potential well; inset shows the enlarged figure of the dotted box. (b)–(d) one-body densities of 11S0 and 21P1 states of endohedrally confined helium atom. The depth of an attractive well is: (b) V 0 = 4.4 Hartree, (c) V 0 = 4.6 Hartree, (d) V 0 = 4.9 Hartree, respectively.
