Measurement of the Pb208(Cr52,n)Sg259 excitation function

The excitation function for the Pb-208(Cr-52,n)(259)Sg 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 (259)Sg were observed and the measured decay properties are in good agreement with previous reports. In addition, a partial excitation function for the Pb-208(Cr-52,2n)(258)Sg reaction was obtained, and an improved (258)Sg half-life of 2.6(-0.4)(+0.6) ms was calculated by combining all available experimental data.
