HYPERFINE INTERACTIONS IN THE GROUND STATE AND 21.7 KEV STATE OF Eu-151 IN EUROPIUM IRON GARNET
Abstract
The hyperfine interaction of the ground state and 21.7 kev state of Eu-151 in europium iron garnet have been measured at 300, 81 and 20K using the technique of Mossbauer absorption. Values of (335 = 50) koe, (570 = 35) koe and (670 = 100) koe were found for effective magnetic fields acting on the Eu nuclei in europium iron garnet at the temperatures of 300, 81 and 20 K respectively. These values are in agreement with theoretical calculations of the non-diagonal matrix elements associated with the admixture of states produced by the exchange interaction. The value of the quadrupole interaction of the ground state of Eu-151 in europium iron garnet was found to be (-240 = 100)mc/sec at 81 K. The results yield an assignment of a spin of 7/2 for the 21.7 kev level and a value of mu (2.54 = 0.15) n.m. for the magnetic moment of this level.
