Hyperfine interaction of Vk centres in Cs2NaYCl6 crystals

In this work we present the results obtained through electron paramagnetic resonance (EPR) spectroscopy of the study of the hyperfine interaction of the Vk centres in the Cesium, sodium, yttrium hexachloride (Cs2NaYCl6) crystals. These electron defect centres are created by v-irradiation at liquid n...

Sumario:In this work we present the results obtained through electron paramagnetic resonance (EPR) spectroscopy of the study of the hyperfine interaction of the Vk centres in the Cesium, sodium, yttrium hexachloride (Cs2NaYCl6) crystals. These electron defect centres are created by v-irradiation at liquid nitrogen temperature of the Cs2NaYCl6 crystals. Our results are: gt=2.008, gl=2.023, At=91.21 (gauss) and Al=3.10 (gauss) and these results are compared with those obtained by Th. Pawlik and J.M. Spaeth [24] for the same system and those of D. Shoemaker [23] for sodium chloride.
