Abstract

In this work, we present a theoretical study of the photoionization for atomic hydrogen confined in onion fullerene compared with the bare H atom and the single fullerene case. We obtained the expected confinement resonances for the integrated probabilities, finding different trends for the main peak and the first ATI peak integrations. We perform these calculations with a recently developed methodology using Generalized Sturmian Functions to numerically solve the time-dependent Schr\"odinger equation.
