Abstract: | The cross sections for fission induced by one neutron transfer and by the electromagnetic field in the reaction 24.3 MeV/u 238U + 197Au are calculated and compared to the experimental data. It turns up that the two calculated cross sections differ by five orders of magnitude at a distance of closest approach of 25 fm. It is shown that in the experiment in which one is able to select the events corresponding to a large distance of closest approach, a separation of Coulomb fission from nuclear fission events can be efficiently obtained. |
