Wigner photoemission time delay from endohedral anions

Kumar, Ashish; Varma, Hari R; Deshmukh, Pranawa C; Manson, ST; Dolmatov, V K; Kheifets, Anatoli


Characteristic features of Wigner photoemission time delay from endohedral anions A@C60q along with their dependence on the anion charge q are unraveled. Specifically, significant enhancement of the time delay in the innermost dipole photoionization channels near threshold is found, owing to the presence of the Coulomb confined resonances (CRs). Moreover, it is shown that interchannel coupling of the inner-shell Coulomb CRs with outer-shell photoionization channels results in resonantly...[Show more]
