Abstract
The quadrupole interaction for (in the excited state) embedded in In, InBI, and Bi is studied using the time-differential-perturbed-angular correlation technique. The interaction frequencies found for at substitutional lattice sites in these metals are rad/sec, rad/sec, rad/sec, rad/sec, and rad/sec. Local contributions to the field gradients are found to be present, implying that the previous evaluations of should be attended to. For samples made by ion implantation of , it is found that > 96%, ≅ 80%, and ≅ 84% of the implanted atoms are substitutional at room temperature for In, InBi, and Bi, respectively. The latter value includes ≅ 18% of at the Bi site while, for InBi, all the substitutional atoms are at In sites. The remaining implants are trapped in domains of radiation damage, characterized by a frequency distribution with a large average value (for InBi rad/sec).
