Abstract : Photoionization studies of Cd@C 60 ASHISH KUMAR, SINDHU KALYADAN, HARI R. VARMA, IIT-Mandi, PRANAWA C. DESHMUKH, IIT-Madras, STEVEN T. MANSON, Georgia State Uni-versity — Atoms trapped in fullerene (A@C 60) cages have attracted con-siderable attention in the recent past owing to their importance in many areas of physics [1]. The additional potential due to the fullerene cage causes significant changes to atomic ionization probabilities by inducing confinement oscillations in the photoionization parameters [2]. The ex-istence of such oscillations has been verified in a recent experiment [3]. These developments have motivated us to extend our studies of the effect of confinement on the photoionization process. We study the photoion-ization of Cd which is trapped inside a fullerene molecule (Cd@C 60) to understand the combined effect of confinement, correlation and relativis-tic effects on photoionization in such endohedral system. The fullerene potential is simulated by using a spherical shell model potential. In the present work, the Relativistic Random Phase approximation (RRPA) method is employed to determine the photoionization parameters
