Wall Induced-oscillations in Photo detachmentof Homo Nuclear DiatomicMolecular Negative ion
Main Article Content
Abstract
The Pd (Photodetachment) of a hydrogen molecular negative ionsnear a soft reflecting wall is being investigated theoretically, focusingon the differential and total Pd.CS (Photodetachment Cross Section) when the laser polarisation is along the molecular axis of the ion.Quantum interference becomes evident on the observable plane when the two components of the electron wave superimpose at a considerable distance and propagate outward. The investigation of these interferences contributes to improving our understanding of the structure of diatomic molecular negative ions.Wall-induced fluctuations are observed in the detached electron spectra. As the distance between the ion and wall (R) increases, the wall effect diminishes,and the results approach those of the Ionsin free space,the oscillation amplitude in the Pd.CS decreases, and their frequency increases as both Walls (R) and the distance between the two opposing ion centers(d) increase. The oscillations eventually cease to exist, and the CS (cross-section) exhibitsuniform behaviorat tremendous values of Rand(????→∞,????→∞)resulting inthe match to the Ionsin free space.
