Quasifission processes in {sup 40,48}Ca+{sup 144,154}Sm reactions
Mass-energy and angular distributions of fission fragments for the {sup 48}Ca+{sup 144,154}Sm{yields}{sup 192,202}Pb, {sup 40}Ca+{sup 154}Sm{yields}{sup 194}Pb reactions have been measured.

| description | Mass-energy and angular distributions of fission fragments for the {sup 48}Ca+{sup 144,154}Sm{yields}{sup 192,202}Pb, {sup 40}Ca+{sup 154}Sm{yields}{sup 194}Pb reactions have been measured. Fusion suppression and the presence of quasifission at energies near and below the Coulomb barrier have been observed for the reactions with the deformed target {sup 154}Sm. In the case of the spherical {sup 144}Sm target no evidence of quasifission has been found. Quasifission cross sections have been extracted from total fission-like events by analysis of their mass and angular distributions. |
