β-γ spectroscopy of the ¹⁹⁵Os nucleus

RADIOACTIVITY ¹⁹⁵Os(β^-)[ionized ¹⁹⁵Os using laser system from ¹⁹⁸Pt(¹³⁶Xe, X), E=9.4 MeV/nucleon at the KEK isotope separation system (KISS) at RIKEN RIBF facility]; measured Eβ, Iβ, Eγ, Iγ, x rays, βγ- and γγ-coin, half-life of ¹⁹⁵Os decay using a multisegmented proportional gas counter (MSPGC) for β radiation, and four clover HPGe detectors for γ rays. ¹⁹⁵Ir; deduced levels, J, π, Iβ feedings, logft. ¹⁹⁵Os; deduced spin and parity of the ground state. Systematics of half-lives of ^{195,196,197,198,199,200,201,202,203,204,205,206}Os, and comparison with theoretical predictions.
