Coincidence Measurements

Gamma–gamma coincidence measurements on the decay of 9.3-hour 127Te to 127I form the basis of the decay scheme presented, which confirms the accepted decay sequence. Directional correlation measurements have been made on the 215–203 keV and 360–58 keV cascades. The respective correlation functions are:[Formula: see text]The directional correlation results have been interpreted in terms of the accepted spin sequence, and limits of multipole mixtures are presented. A short discussion of the collective properties of the levels is presented.

Good Agreement

The energies and intensities of 13 gamma rays in Re188 have been measured by studying their external conversion spectra with a high resolution beta-ray spectrometer. An analysis of the beta-ray spectrum reveals groups with end points 2116 kev. (79%) and 1961 kev. (20%), and several low energy groups whose total intensity is of the order of 1%. The observed data can be consistently accounted for in terms of a decay scheme involving the following levels of OS188: 0.0, 155.0, 633, 1086, 1306, 1461, 1765, 1941, and 1958 kev. This scheme is firmly supported by coincidence measurements. The spins of the first three levels listed are 0+, 2+, and 2+ and that of the 1461 kev. level is probably 0+.The decay of Re186 is accompanied by gamma rays of the following energies and quantum intensities: 122.9 kev. (0.6%), 137.2 kev. (10%), 630.8 kev. (0.024%), and 768.2 kev. (0.024%). These values are in good agreement with those quoted in the literature, except for the intensities of the last two radiations.

The radiations from Pm151 have been studied by external and internal conversion measurements and electron–electron, electron–beta, electron–gamma, and beta–gamma coincidence experiments. Thirty-six transitions have been identified. A decay scheme incorporating 30 of these has been established by energy and coincidence measurements with levels in Sm151 at 0, 0.0048, 0.0658, 0.0697, 0.0915, 0.1048, 0.1677, 0.1684, 0.2090, 0.3239, 0.3449, 0.4445, 0.741, and 0.821 Mev. The half-life of the 0.0048-Mev level is (19 ± 10) × 10−9 sec. The total decay energy is 1.195 ± 0.010 Mev.

The decay of 1.3 h 87Kr, 2.8 h 88Kr, and 15 min 88Rb to levels in 87Rb, 88Rb, and 88Sr, respectively, has been investigated using high-resolution Ge(Li) detectors, a plastic beta-ray detector, and gamma–gamma as well as beta–gamma coincidence techniques. Isotope separation was achieved using gas-sweeping methods. Consistent level schemes have been constructed for each isotope under study.
