摘要：

A series of fusion evaporation reactions induced by the 54Cr17+ Cr 17 + beam have been performed using the gas-filled recoil separator SHANS2. The excitation functions of 54 Cr + 159 Tb and 54 Cr + 165 Ho reactions were measured. The systematics of cross sections for reactions with 40 Ar, 48 Ca, 50 Ti, and 54 Cr projectiles are compiled and discussed. It is suggested that employing the 54 Cr beam holds the potential for synthesizing neutron-deficient actinide nuclei. In addition, we attempted to synthesize undiscovered americium isotopes with 175 Lu( 54 Cr , 3n-4n) n -4 n ) 225 ,226Am , 226 Am reactions. No events were observed originating from 225 Am and 226 Am, and the upper limits were estimated to be 2.1 and 1.7 pb, respectively. The significantly low fission barrier of the compound nucleus 229 Am, which leads to the small survival probability, might be a possible reason for the low cross sections.
