GE(LI)-GE(LI) STUDY OF 134I DECAY

The levels in Xe134 were investigated from the decay of 53-min I134 by means of Ge(Li) γ-ray spectrometry. From γ-ray energy and intensity measurements employing a high-resolution Ge(Li) detector, and from coincidence relationships determined by γ-γ coincidence measurements using two Ge(Li) detectors, it was established that levels at 846.95, 1613.4, 1731.0, 1919.8, 2136.3, 2271.7, 2303.0, 2352.8, 2408.5, 2547.4, 2588.1, 2653.1, 2773.4, 2867.3, 3084.3, 3256.0, 3300.8, 3314.4, 3359.9, 3375.3, 3475.6, and 3493.0 keV are populated in the decay of I134. Possible levels at 2704.7, 3160.4, 3190.0, 3463.1, 3790.3, and 3874.5 keV are discussed on the basis of energy sums. From the logft values obtained, limits for the Jπ values of many levels in Xe134 were placed. No evidence for the population of the 7- isomer of Xe134 was found in I134 decay. © 1969 The American Physical Society.
