The lightest isotope of Bh was produced in the new Bi209(Cr52,n)Bh260 reaction at the Lawrence Berkeley National Laboratory’s 88-Inch Cyclotron. Positive identification was made by observation of eight correlated alpha particle decay chains in the focal plane detector of the Berkeley Gas-Filled Separator. Bh260 decays with a 35-9+19ms half-life by alpha particle emission mainly by a group at 10.16 MeV. The measured cross section of 59-20+29pb is compared to model predictions. The influence of the N=152 and Z=108 shells on alpha decay properties is discussed.
