Abstract: The production of the very neutron-deficient nuclides Bi184-192 and Po186-192 in the vicinity of the neutron midshell at N = 104 has been studied by using heavy-ion-induced complete fusion reactions in a series of experiments at the velocity filter SHIP. The cross sections for the xn and pxn evaporation channels of the Ti-46+Sm-144 ->Po-190(*),Mo-98+Mo-92 ->Po-190(*),Cr-50,Cr-52+Nd-142 ->Po-192,194(*), and Mo-94,Mo-95+Nb-93 ->Bi-187,188(*) reactions were measured. The results obtained, together with the previously known cross section data for the heavier Bi and Po nuclides, are compared with the results of statistical model calculations carried out with the HIVAP code. It is shown that a satisfactory description of the experimental data requires a significant (up to 35%) reduction of the theoretical fission barriers. The optimal reactions for production of the lightest Bi and Po isotopes are discussed.
