(a) The 11S0–31P1 oscillator strengths of confined helium with changing depth of outer confining potential well; inset shows the enlarged figure of the dotted box. (b)–(e) one-body densities of 11S0 and 31P1 states of endohedrally confined helium atom. The depth of an attractive well is: (b) V 0 = 4.3 Hartree, (c) V 0 = 4.4 Hartree, (d) V 0 = 4.5 Hartree, (e) V 0 = 4.7 Hartree, (f) V 0 = 4.9 Hartree, in which the inset shows the enlarged figure of the dotted box, respectively.
