Abstract
This paper describes EPR measurements within the system CdF2 : Eu 2+ between 77 K and 300 K at 9 GHz and 35 GHz for B || [001]. The measurements enable a test of the formerly determined EPR parameters by the strict numerical solution of the eigenvalue problem including the hyper-fine terms. In particular “forbidden” transitions (ΔM = 2) also occur in a strict cubic crystalline field. An interpretation of the superhyperfine structure at 9 GHz and 35 GHz is compatible with the constants T|| = 6.26 MHz and T| = - 6.04 MHz of the interaction with the F ions of the 1 st shell.Keywords
