Static dipole and quadrupole polarizability of confined hydrogen atom with Z=N/3 (N=1–5)*

First calculations of static dipole and quadrupole polarizability for the spherically confined hydrogen atom within the hard boundaries with nuclear charge Z=N/3, N=1–5, are carried out using the Sternheimer perturbation‐numerical procedure. The polarizability values strongly depend upon the radius of confinement. The polarizability calculations for the exotic hydrogenic ions with nuclear charges ⅓, ⅔, {article}{empty}{document}4/3{document} , and {article}{empty}{document}5/3{document} exhibit strong dependence on the radius of confinement and the nuclear charge.
