Notes: Abstract 154Ho was studied via141Pr(16O,3n) reaction at beam energy of 75 MeV. We found two new rotationally aligned bands made of neutron h9/2 and f7/2 orbitals coupled to a proton h11/2 orbital. As with several new high-spin states, up to I=20, the ground state band with odd parity starts to show anomalous signature splitting at I=13 in this doubly odd154Ho. The observed rotational bands in154Ho are quite consistent with the onset of collectivity which appears in general at neutron number of 87 in neutron-deficient rare-earth nuclei.

Notes: Abstract High spin states in115Te have been studied using the89Y (29Si, p2n) reaction at a beam energy of 108 MeV.γ-γ coincidence, Eγ, Iγ and excitation functions have been measured. The level scheme has been extended to 82 MeV excitation energy relative to the 11/2 state and several new states are established. The systematical behaviour in odd- N Te isotopes is discussed.

Notes: Abstract Theβ + decay of86Mo has been firstly investigated by means ofβγ spectroscopy. The86Mo nuclei were produced by fusion-evaporation reactions of54 Fe (35Cl, 1 p2n) and58Ni (32S,2p 2n) at beam energies of 103 and 120 MeV, respectively. Threeγ rays of 47.3, 49.8 and 187.0 keV were unambiguously identified to follow theβ + decay of86Mo by results ofXγ andβγ coincidence and cross-bombardment. A half life and a maximumβ +-ray energy of86Mo were determined to be 19.6±1.1 s and 3.9±0.4 MeV, respectively. A decay scheme of86Mo is proposed in this article. Furthermore, a decay of86Nb has been studied using the same combinations of projectiles and targets, and a newβ-decaying isomer86m Nb was observed with a half life of 56.3±8.3 s.
