The isotopes &sup(261,262)261,262Bh were reinvestigated by using the cold fusion reaction *5*4Cr+*2*0*9Bi. The evaporation residues were separated by the gas-filled recoil separator SHANS2 (Spectrometer for Heavy Atoms and Nuclear Structure-2) and identified by means of the recoil-α-correlation method. The α-decay properties of &sup(261,262)Bh were measured and the results are consistent with the previously reported values. Based on the measured half-lives, the existence of two distinct states of *2*6*2Bh was confirmed, whereas *2*6*1Bh lacked any isomer with α-decay properties. Two spontaneous fission events potentially from *2*6*2Bh and/or *2*6*1Bh were detected and the production cross sections at beam energies of 264.1 and 270.4 MeV were obtained.
