Resonance enhancement of the endohedrally confined hydrogen-like system

Abstract

Using B-spline method, we take Be3+ in buckyminister fullerence as a n example and have calculated the 2s—3p oscillator strength of the endohedrally confined hydrogen-like system in the confining well with different shapes and l ocations. Resonance enhancement appears as the 2s and 3p states are both bound i n outer well, and a resonance enhancement peak has been found at the “collapse point”. Our results show that resonance enhancement is insensitive to the shape of the confining well, and it is also influenced by confinement ability. The lo cation of the confining well may strongly affect the resonance enhancement.

Resonances of a hydrogen atom in strong parallel electric and magnetic fields using B-spline basis sets

“…Using the B-spline basis set as an angular basis-set can reduce considerably the basis set dimension, and then accelerate convergence. [23,24] These advantages have been verified further by our recent calculation of electronic structure of hydrogen molecular ion [25] and energy spectra of confined atoms, [26,27] where the quantum systems are far from spherical symmetry.…”
