Structural properties of Na atom under impenetrable spatialconfinement
The structural properties and radial distributions of valence electron in different excited levels of Na atom [n = 3 − 5, l = 0 − 4; n and l being the principal and orbital angular momentum quantum numbers, respectively] under impenetrable spherical confinement has been studied, where the interaction between the frozen core and the valence electron is mimicked by model potential available in the literature. The effect of the core on the valence electron has been investigated by estimating the structural properties of Na10+ ion under similar confinement. Scaled radial densities at the nucleus and related ratios are presented for few excited states of the valence electron of Na atom and the corresponding analytic results have been tested numerically.
