Сверхтонкое и квадрупольное взаимодействия в ЭПР изотопов -=SUP=-153-=/SUP=-Eu-=SUP=-2+-=/SUP=- и -=SUP=-151-=/SUP=-Eu-=SUP=-2+-=/SUP=- в иттрий-алюминиевом гранате

Abstract

In specially grown single crystals of yttrium-aluminum garnet, the orthorhombic centers 153Eu2+ and 151Eu2+ were investigated. The parameters of hyperfine and quadrupole interactions, which describe the hyperfine structure of the EPR spectrum of both isotopes, are determined.
