Production of ²⁶⁶Bh in the ²⁴⁸Cm(²³Na, 5n)²⁶⁶Bh reaction and its decay properties

RADIOACTIVITY ^266,267Bh(α)[from ²⁴⁸Cm(²³Na, 5n), (²³Na, 4n), E=125.9, 130.6, 135.3 MeV]; ²⁶²Db(α), (SF)[from ²⁶⁶Bh α decay]; ²⁶³Db(EC), (α), (SF)[from ²⁶⁷Bh α decay]; ²⁶³Rf(SF)[from ²⁶³Db EC decay]; ²⁵⁸Lr(α), (EC)[from ²⁶²Db α decay]; ²⁵⁹Lr(α), (SF)[from ²⁶³Db α decay]; ²⁵⁸No(SF)[from ²⁵⁸Lr(EC); measured Eα, αα-, ααα- and α(SF)-correlations for 32 observed events using rotating wheel apparatus MANON and gas-jet transport system coupled to gas-filled recoil ion separator GARIS at RIKEN; deduced decay times, half-lives, decay branching ratios, production cross sections for ²⁶⁶Bh and ²⁶⁷Bh. Comparison with previous experimental results for half-lives and branching ratios for decay modes.

NUCLEAR REACTIONS ²⁴⁸Cm(²³Na, 5n), (²³Na, 4n), E=125.9, 130.6, 135.3 MeV; measured reaction products, σ(E) at RIKEN. Comparison with HIVAP calculations, and with previous experimental results.
