Abstract
The temperature dependence of the magnetic-excitation spectrum in a singlet-doublet system is calculated by use of a generalized Vaks-Larkin-Pikin diagram technique. The first-order terms in the high-density expansion representing scattering on single-site fluctuations give an almost complete description of the line shapes in double-hcp praseodymium at any temperature.Keywords
