Abstract: | Low-temperature time differential perturbed angular correlation experiments with the 164 keV-134 keV cascade of 197mHg in a zinc matrix give evidence that the hitherto accepted value of the quadrupole moment of the first state of 197Hg is erroneous. A new value is derived from a time differential perturbed angular correlation experiment with the 374 keV?158 keV cascade of 199mHg implanted into a Be single crystal and comparison with an analogous experiment for 197mHg. Taking we derive . This change of quadrupole moment is discussed in the framework of the shell model. |
