The excitation function for the 208Pb(52Cr,n)259Sg reaction has been measured using the Berkeley Gas-filled Separator at the Lawrence Berkeley National Laboratory 88-Inch Cyclotron. The maximum cross section of 320-100+110 pb is observed at a center-of-target laboratory-frame energy of 253.0 MeV. In total, 25 decay chains originating from 259Sg were observed and the measured decay properties are in good agreement with previous reports. In addition, a partial excitation function for the 208Pb(52Cr,2n)258Sg reaction was obtained, and an improved 258Sg half-life of 2.6-0.4+0.6 ms was calculated by combining all available experimental data.
