Dependence of the evaporation residue production on the excitation energy of the compound nucleus in the reaction40Ar+164Dy

With the velocity filter SHIP at the heavy ion accelerator UNILAC the energy dependence of the evaporation residues production in the reaction⁴⁰Ar+¹⁶⁴Dy was investigated. The results show a much smaller shift of the (²⁰⁴Po, xn) excitation functions with respect to theoretical predictions than has been reported by other authors.
