%X In this paper we will present a study of several Tm and Pr compounds, where the rare earth atoms have as their two lowest energy levels a quasi-doublet ground state. These compounds are also compared with Er and/or Dy compounds, which have a Kramers doublet as ground state. Four compounds (TmNi5, TmCu2, TmCuAl and PrRu2Si2) are discussed in sequence, where the energy separation of the two levels of the quasi-doublet ground state doublet is increasing. These compounds were studied with rare earth M&ouml;ssbauer spectroscopy and &#181;SR as the main measuring techniques.
