The energy levels of 117In have been investigated following the β decay of 3.4 h 117Cdm and 2.5 h 117Cdg. Using high resolution Ge(Li) detectors singly and in coincidence, 127γ transitions have been observed. Eighty-five of these transitions have been classified by both coincidence data and energy fit, 29 weak transitions by energy fit alone, and 12 remain unclassified. Thirty-seven levels in 117In have been established; of these, 24 are low spin states fed from the ground state and 13 are high spin states fed from the isomer. Spin and parity assignments for the newly established levels are discussed.

Boson Model

The core-excited interacting boson model up to two boson excitation is applied to 184 Pt and 172 W nuclides. In addition to energy levels (backbending), the calculated transition quadrupole moments of 172 W also reproduces the experimentally observed behavior, namely, a reduction at high spin. Incidentally a structure change between the lighter and the heavier Pt isotopes manifests itself in the study.

Search for low-spin signature inversion in the πi13/2 ⊗ νi13/2 bands in odd-odd 182,184,186 Au has been conducted through the standard in-beam γ-spectroscopy techniques. The experiments for 182 Au and 186 Au have been performed in the Japan Atomic Energy Agency (JAEA) via the 152 Sm (35 Cl ,5 n )182 Au and 172 Yb (19 F ,5 n )186 Au reactions, respectively. A study of 184 Au has been made using a multi-detector array GASP in LNL, Italy, via the 159 Tb (29 Si ,4 n )184 Au reaction. The πi13/2 ⊗ νi13/2 bands in these three nuclei have been identified and extended up to high-spin states. In particular, the inter-band connection between the πi13/2 ⊗ νi13/2 band and the ground-state band in 184 Au has been established, leading to a firm spin-and-parity assignment for the πi13/2 ⊗ νi13/2 band. The low-spin signature inversion is found in the πi13/2 ⊗ νi13/2 bands in 182,184,186 Au according to our spin-assignment and the signature crossing observed at high-spin states.

Level schemes of even–even neutron-rich 88-92 Kr and 86 Se have been investigated by measuring triple-γ coincidence data from the spontaneous fission of 252 Cf with the Gammasphere detector array. The level scheme of 88 Kr has been extended up to 7169 keV state. Several new excited states with new transitions have been identified in 90,92 Kr and 86 Se . Spins and parities have been assigned to levels in these nuclei by following regional systematics and angular correlation measurements. The level structures of the N = 52, 54, Se , Kr , and Sr isotones are discussed.

Energy levels in 149Tb have been studied by the 142Nd (10B,3n) reaction using 54 MeV 10B beams from the McMaster University FN accelerator. Excitation functions, angular distributions, prompt γ–γ coincidence, electron conversion, and linear polarization measurements were obtained. On the basis of these measurements we have identified two rotaition-aligned πh11/2 bands, a negative parity band up to spin 27/2−, and a positive parity band up to spin 27/2+. The energy spacings between levels in these bands strongly resemble those in the ground state and the 3− octupole band of the adjacent 148Gd core nucleus. Other high spin positive parity states up to spin of 41/2 are also observed. These high spin states show some evidence of rotational structure in 14 9Tb.

The decay of Pr137 entirely to a 9.0-hour ground state of Ce137 was independently discovered. By allowed electron capture, Ce137 decays predominantly to a low-lying state of La137, with only a 3% branching to a 440-kev excited state. The 440-kev transition is at least predominantly E2 in character.A 34.4-hour isomeric state produced by the La139(p, 3n)Ce137m reaction decays by a 254.5-kev M4 transition to the 9-hour -ground state. A 0.6% branching was found from the isomeric state directly to a small group of apparently high spin states in La137.Studies of mass-separated isotopes confirmed the existence of 1.5-hour Pr137 and 1.0-hour Pr136. The K-capture to positron branching ratios observed in the decay of Pr139, Pr138, Pr137, and Pr136 show that these isotopes decay by allowed transitions to their cerium daughters. Characteristic gamma rays were observed.
