New neutron-rich nuclei Zr103,104 and the A100 region of deformation

Partial decay schemes in the neutron-rich nuclei Zr103 and Zr104 have been measured for the first time and rotational bands in Zr100 102 have been extended to spins of up to 10Latin small letter h with stroke by observing prompt rays from the spontaneous fisson of Cm248. These nuclei are among the most deformed known at low spin and excitation energy. The level structures in the odd-A nuclei show that the h11/2 intruder orbital plays an important role in stabilizing the deformation in this region

High-spin properties of octupole bands in 240Pu and 248Cm

The properties of superdeformed bands in 191,192Hg and 192,193Tl have been studied using the cranked Hartree-Fock-Bogoliubov method with the Lipkin-Nogami prescription, the Skm* interaction, and a surface-delta, density-dependent pairing force. In particular, quasiparticle excitations involving intruder orbitals are analyzed in detail. Comparisons between data and calculations are performed for J (2) moments, quadrupole moments, spins, transition energies, and alignments

Thermodynamic Properties of Actindes and Actinide Compounds

The necessity of obtaining accurate thermodynamic quantities for the actinide elements and their compiunds was recognized at the outset of the Manhattan Project, when a dedicated team of scientists and engineers initiated the program to exploit nuclear energy for military purposes.JRC.E.6-Actinides researc
