Abstract
Time differentialγγ-angular correlation measurements have been performed to determine the electric interaction of the 2.3 MeVI=5− state of120Sn in different polycristalline antimony compounds. A calibration of the field gradient was achieved by Mößbauerexperiments with the 23.8 keVI=3/2+ state in119Sn using identical sources. From the ratio of the measured electric interactions the ratio of the quadrupole moments is deduced as:
. Using 0.06 (2) b for the quadrupole moment of the 23.8 keV level in119Sn one gets for the quadrupole moment of the 2.3 MeV level in120Sn ¦Q(2.3 MeV level,I=5−,120Sn)¦=0.021 (8) b.
