Two-photon processes based on quantum commutators
Filippo Fratini, Laleh Safari, Pedro Amaro +1
We developed a new method to calculate two-photon processes in quantum mechanics that replaces the infinite summation over the intermediate states by a perturbation expansion. This…

Angular correlations in the two--photon decay of helium--like heavy ions
A. Surzhykov, A. Volotka, F. Fratini +5
The two-photon decay of heavy, helium-like ions is investigated based on second-order perturbation theory and Dirac's relativistic equation. Special attention has been paid to the…
