Theoretical ab initio Evolution of Satellite Intensity near Threshold for Cu K-shell transitions

Daniel Pinheiro, Gonçalo Baptista, César Godinho +9

In this work, we have investigated the evolution of satellite intensity near the ionization threshold for Cu K-shell transitions through theoretical methods. Employing standard sta…

Penning-trap measurement of the -value of the electron capture in for the determination of the electron neutrino mass

Christoph Schweiger, Martin Braß, Vincent Debierre +19

The investigation of the absolute scale of the effective neutrino mass remains challenging due to the exclusively weak interaction of neutrinos with all known particles in the stan…

Non-perturbative calculation of the two-loop Lamb shift in Li-like ions

V. A. Yerokhin, P. Indelicato, V. M. Shabaev

A calculation valid to all orders in the nuclear-strength parameter is presented for the two-loop Lamb shift, notably for the two-loop self-energy correction, to the 2p-2s transiti…
