摘要：
Pure nuclear electric quadrupole interaction of ion-implanted 203Hg and 188Ir in Highly Oriented Pyrolytic Graphite layers has been observed in low temperature nuclear orientation experiments. The electric field gradients at the nuclear sites were found to be positive, with values of +0.79(17)×1019 V/cm2 (νQ=0.66 (14) GHz) for 203Hg and +0.788 (40)×1019 V/cm203 (νQ=0.987 (40) GHz) for 188Ir. At 4 mK, the anisotropies in the directional distribution of γ-rays from these isotopes were saturated, but only at 35.2 (2.4) % for 203Hg, respectively 8.59(18)% for 188Ir, of the expected maximum value. © 1990, Elsevier Science Publishers B.V.
