Paramagnetische Resonanz von Mn++-Ionen in synthetischen und natürlichen ZnO-Kristallen (II). Analyse der verbotenen Übergänge ΔΜ = ±1, Δm= ±1

Abstract

Forbidden hyperfine transitions △M = ± 1, △m= ± 1, ± 2 have been observed at X-band frequencies in the epr-spectra of Mn⁺⁺-ions in ZnO single crystals. From the unequal separation between the M= - ½ → ½, △m= ± 1 transitions in the spectrum, a quadrupole coupling constant of P=0,000016 ± 0,000002 cm^-1 was obtained. Third order corrections to the hfs-energy had to be used in this analysis
