Nuclear chemistry

Research in nuclear chemistry was carried out in the following areas: Fragment mass and kinetic energy distributions from the spontaneous fission of 252No; Production, identification, and the alpha and spontaneous-fission decay characteristics of nuclide 262105; search for superheavy elements in nature; Attempted synthesis of superheavy elements in the reaction 48Ca + 248Cm; Absolute L-series x ray and low-energy gamma ray yields for most transuranium nuclides; Transfer reactions studies: the production of 245Cf, 244Cf in reactions of 239Pu with 12C, 16O, 20Ne, and 14N; Strongly damped reactions from 20Ne bombardments of 48Ti, Ni, and 94Zr (cross sections and fragment kinetic energies); Observed differences in 200Po compound nuclei produced by 40Ar and 84Kr projectiles (excitation functions); Study of evaporation residues from 86Kr bombardment of 65Cu, 90Zr, and 109Ag; Gamma-ray multiplicities in evaporation residues formed in bombardments of 150Nd by 20Ne; Bands in odd-A thallium isotopes; Properties of 164Er in the band crossing region; Lifetimes of ground-band states in 150Nd; Levels in 195Tl, 197Tl from Pb decay; Thermal-neutron capture and fission cross sections and resonance integrals for 243Cm; Differential fission cross section measurements at the ORELA for 243Cm; 232Th(n,γ) cross sections from 2.6 to 800 keV; Resonance neutron capture by 209Bi; High-resolution neutron capture cross section in 63Cu, 65Cu; 292.4-eV neutron resonance parameters of 91Zr; and Monte Carlo modeling of x-ray transport in a heterogeneous phantom--applications to the detection of respired actinide nuclides. 23 figures, 9 tables
