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 Mössbauer spectroscopy and µSR as the main measuring techniques.

Deformed even–even nuclei with quadrupole and octupole deformations are investigated on the basis of a nonadiabatical collective model. It is shown that the model satisfactorily describes energy levels of the yrast and first nonyrast bands with alternating parity in the rare-earth nuclei 150 Nd , 152, 154 Sm , 154 Gd , 156 Dy , 162, 164 Er and the actinides 232, 234, 236, 238 U . In the nuclei 156, 158 Gd , 224 Ra , 228 Th and 240 Pu the energy levels of second nonyrast bands are also described. The structure of the considered alternating-parity bands is examined in terms of odd–even staggering diagrams.

MgxZn1-xSi: Ho3+, MgxZn1-xSe: Er3+, and MgxZn1-xSe: Tm3+ single crystals were grown by the closed-tube sublimation method. The single crystals crystallized into a zincblende structure at the composition x = 0.11 and a wurtzite structure at the composition x = 0.25, 0.32, and 0.41. The trivalent ions (Ho3+, Er3+, and Tm3+) of the rare-earth elements Ho, Er, and Tm site in Td and C3v symmetries in the single crystals with zincblende and wurtzite structures, respectively. Sharp emission peaks appeared in the photoluminescence spectra of the single crystals. These emission peaks are identified to originate from the radiation recombination between the energy levels of the trivalent ions sited in Td and C3v symmetries.
