Abstract
Beta decay of Ga86 was studied by means of β-neutron-γ spectroscopy. An isotopically pure Ga86 beam was produced at the Holifield Radioactive Ion Beam Facility using a resonance ionization laser ion source and high-resolution electromagnetic separation. The decay of Ga86 revealed a half-life of 43-15+21 ms and large β-delayed one-neutron and two-neutron branching ratios of P1n=60(10)% and P2n=20(10)%. The βγ decay of Ga86 populated a 527 keV transition that is interpreted as the deexcitation of the first 2+ state in the N=54 isotone Ge86 and suggests a quick onset of deformation in Ge isotopes beyond N=50. © 2013 American Physical Society.
