  "abstract": "New neutron rich isotopes 107267Bh and 107266Bh were produced in bombardments of a 249Bk target with 117-MeV and 123-MeV 22Ne ions at the Lawrence Berkeley National Laboratory 88-Inch Cyclotron. Identification was made by observation of correlated \u03b1-particle decays between the Bh isotopes and their Db and Lr daughters using a rotating wheel system. 267Bh was produced with a cross section of \u224870 pb and decays with a 17\u22126+14 s half life by emission of \u03b1 particles with an average energy of 8.83\u00b10.03 MeV. One atom of 266Bh was observed, decaying within 1 s by emission of a 9.29-MeV \u03b1 particle.",
