Times Cited Count:64 Percentile:87.54(Physics, Multidisciplinary)Excited states in Fm fed by the decay of No have been established through - and -electron coincidence spectroscopy using a gas-jet transport system and an on-line isotope separator. The spin-parity of the 124.1 keV level in Fm has been identified on the basis of the measured internal conversion coefficients. The configuration has been assigned to the ground state of No as well as to the 124.1 keV level. It was found that the ground state configuration of No is different from that of lighter isotones.

Times Cited Count:9 Percentile:50.95(Physics, Nuclear)EC and decays of Am have been studied by means of -ray spectroscopy. Excited states in Pu have been established for the first time, and tentative spin-parity and Nilsson assignments were given to these levels. The ground state of Am was evaluated to be the state from the experimental results. It was found that the state in Np is located at 15~keV, which allowed us to determine the value of Am as 6569~keV, in combination with the measured -particle energy.

Nuclear resonance fluorescence experiments have been performed on Hf and W natural targets in the 2.5-3.1 MeV energy range using quasi monochromatic -ray beams generated from laser Compton scattering at the HIS facility, Duke University. The complete polarization of the incident -rays has provided the determination of the parity of states in this energy range. Results of these experiment have revealed the parity of about 15 levels in Hf and W nuclei. Such data provide knowledge about the nondestructive detection system of nuclear material by understanding the so-called scissors mode encountered in deformed nuclei including uranium and plutonium isotopes.
