Abstract

We present the numerical values of the density shift and broadening slopes of laser-stimulated dipole transitions in antiprotonic helium atoms at temperature 1.5°K and 5.4°K, evaluated in the semiclassical approach with a realistic interatomic potential calculated ab initio. Compared to our 2000 paper, the present results cover the much wider set of transition lines that have been subject of precision spectroscopy since then.
