V. Mandot et al., HYPERFINE INTERACTION STUDY OF ELECTRIC-FIELD GRADIENT IN HAFNIUM PHOSPHIDE USING TA-181 PROBE, Pramana journal of physics, 50(3), 1998, pp. 227-230
The hyperfine interaction of Ta-181 in HfP has been investigated by ti
me differential perturbed angular correlation method which yielded int
eraction frequency nu(Q) = 630.20(15) MHz. The observed electric field
gradient is calculated to be 1.66(25) x 10(20) V/m(2).
