摘要：

The perturbed angular correlation method (PAC) was applied to investigate the lattice location of implanted In-111 probe ions in Hf2Ni and Zr2Ni intermetallic compounds. It is Concluded that the In-111/Cd-111 probe nuclei experiencing the highly asymmetric electric field gradient (EFG) Occupy the unique hafnium or zirconium 8(h) sites in the investigated phases. Above room temperature, the EFGs decrease linearly with temperature. The results are compared with that of previous PAC measurements with Ta-181 probes.
