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 5 2 − 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 Q( 5 2 − , 199 Hg) = +0.95(7) b we derive |Q( 5 2 − , 197 Hg)¦= 0.081(6) b . This change of quadrupole moment is discussed in the framework of the shell model. |
