A study of fusion reactions between206, 207Pb nuclei and40Ar ions near the coulomb barrier
Excitation functions for the reactions206Pb(40Ar, 2n)244Fm and207Pb(40Ar, 3n)244Fm have been measured and analysed in terms of a statistical model. The optical potential parameters have been found to be as follows:V0=− 70 MeV,r0=1.26×10−13 cm andd =0.36×10−13 cm. Some data on the properties of the excited compound nucleus of fermium have been obtained.
