Comparison of reactions for the production of Db258,257: 208Pb(51V,xn) and 209Bi(50Ti,xn) Academic Article uri icon


  • Excitation functions for the 1n and 2n exit channels of the 208Pb(51V,xn)259-xDb reaction were measured. A maximum cross section of the 1n exit channel of 2070-760+1100 pb was measured at an excitation energy of 16.0 ± 1.8 MeV. For the 2n exit channel, a maximum cross section of 1660-370+450 pb was measured at 22.0 ± 1.8 MeV excitation energy. The 1n excitation function for the 209Bi(50Ti,n)258Db reaction was remeasured, resulting in a cross section of 5480-1370+1730 pb at an excitation energy of 16.0 ± 1.6 MeV, in agreement with previous values [F. P. Heßberger, Eur. Phys. J. A 12, 57 (2001)]. Differences in cross section maxima are discussed in terms of the fusion probability below the barrier. © 2008 The American Physical Society.
