Abstract

The total conversion coefficient of the 127.49 keV E3 isomeric transition in the decay of134mCs was measured using the gamma intensity balance method with the help of a high resolution low energy photon detector. Theα Tvalue was found to be 5.84±0.47 as against the theoretical value of 6.96, thus showing an anomaly of (16.1±6.7)%. TheK-conversion coefficient,α kwas also measured using the X-ray peak to gamma ray intensity method and found to be 2.24±0.04 as against the theoretical value of 2.72, which shows an anomaly of (17.6±1.4)% consistent with the experimental anomaly inα T. TheE3 hindrance factor of the isomeric transition was estimated to be (3.44±0.23) ·104.
