Higher order photon transitions in H-like and He-like ions.

PDF Version Also Available for Download.

Description

Higher order photon transitions such as M1, M2 and two-photon decay are conveniently studied using highly-charged electron ions. Here we discuss two examples from recent experiments which were done using the ATLAS facility at Argonne National Laboratory. The first is a test of Relativistic Quantum Mechanics involving a precision measurement of the spectral shape of the two-photon decay of the 1s2s{sup 1}S{sub 0} state in He-like nickel and the second is a test of the theory of damping in quantum mechanics involving observation of E1-M1 interference in the electric field quenching of metastable H-like ions.
