Measurement of the quadrupole moment of the 112Sn(6+) isomer

The quadrupole coupling constant of the 112Sn(6+) isomer in the hexagonal Cd host is measured by using the time-differential perturbed angular distribution (TDPAD) method. Values of the quadrupole coupling constants e2qQ/h = 66.25 +- 4.00 MHz and 57.56 +- 6.90 MHz are found at 2900 and 5000, respectively. The quadrupole moment of the 6+ state in 112Sn is derived in terms of the electric field gradient for Sn in Cd given by Herrlander. The deduced quadrupole moment Q is 0.29 +- 0.07b. The simple shell model estimate shows that the 112Sn(6+) state is possibly a mixed configuration of ( g6/sub 7/2/)6+ and ( g7/sub 7/2/xd5/sub 5/2/)6+
