PRODUCTION OF HEAVY ACTINIDES IN INCOMPLETE FUSION REACTIONS

We present preliminary results of calculations by the phenomenological model of the estimated yield of some heavy actinide isotopes. It is assumed that these isotopes are produced as a result of multinucleon transfers followed by neutrons and charged particle emission A.S. Iljinov and E.A. Cherepanov (Proc. Int. Symp. on Synthesis and Properties of New Elements, Dubna, 1980, Joint Institute for Nuclear Research, Dubna, 1980, D7-80-556, p. 29). The yield P-Z,P-N(E(*)) of primary excited actinides is found using the model of N.V. Antonenko and R.V. Jolos (Z. Phys. A, 338 (1991) 423). Absolute cross-sections for different binary reaction channels are obtained by summing the cross-sections for all subchannels with an appreciable yield according to J. Wilczynski et al. (Phys. Rev. Lett., 45 (1980) 606).
