限制环境下类氢体系的共振增强现象

Resonance enhancement of the endohedrally confined hydrogen-like system

采用B样条方法,以囚禁于巴基球内的Be3+为例,计算了限制环境下类氢体系在不同外阱形状和位置下2s—3p振子强度随外阱深度的变化.2s,3p态都被限制在外阱时出现共振增强,在坍塌点发现共振增强峰.计算结果表明,共振增强现象对外阱形状不敏感,但是对外阱的限制能力有要求,同时还受到外阱位置的影响.

Using B-spline method, we take Be3+ in buckyminister fullerence as an example and have calculated the 2s-3p oscillator strength of the endohedrally confined hydrogen-like system in the confining well with different shapes and locations. Resonance enhancement appears as the 2s and 3p states are both bound in 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 location of the confining well may strongly affect the resonance enhancement.
