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 a ssumed that these isotopes are produced as a result of multinucleon tr ansfers followed by neutrons and charged particle emission A.S. Iljino v and E.A. Cherepanov (Proc. Int. Symp. on Synthesis and Properties of New Elements, Dubna, 1980, Joint Institute for Nuclear Research, Dubn a, 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 bin ary reaction channels are obtained by summing the cross-sections for a ll subchannels with an appreciable yield according to J. Wilczynski et al. (Phys. Rev. Lett., 45 (1980) 606).
