Cold fusion reactions with 48Ca

Abstract Fusion reactions of 48 Ca projectiles with 180 Hf, 184 W, 197 Au, 208 Pb and 209 Bi targets were studied. Highest cross sections were found in the 208 Pb( 48 Ca,2n) 254 No channel with σ max 3.2 ± 0.3 μb. The results of the heavier systems are discussed in terms of the extra — push model. For the lighter systems missing cross section is observed if compared to estimates made by the evaporation code HIVAP.
