Abstract

The pressure-dependence of the time-integrated perturbation factor of excited41K nuclei slowing down in Ar gas was calculated and compared to our experimental data. The models used were (1) Abragam—Pound plus static interaction, (2) the Scherer model viewed as a non-stationary sequence of static interaction, and (3) our non-stationary extension of the Scherer—Blume model. The calculations used detailed and quantitative information on nuclear and atomic parameters characterizing the perturbation mechanism. A good agreement is attained between experimental data and calculations.
