Peripheral interactions in the collision of 16O+238U at 110.4 MeV bombarding energy.

Abstract

Inclusive and semiexclusive elemental production cross sections of projectilelike fragments emerging in the collision [sup 16]O+[sup 238]U at 110.4 MeV have been investigated. Energy spectra and angular distributions of projectile residues with charge from [ital Z]=3 to [ital Z]=8 have been measured. It has been found that, as expected, the dominant reaction mechanism in the peripheral collisions is a mass transfer from projectile to target mainly dominated by a transfer of an [alpha] particle. The in-plane coincidences between projectilelike and fission fragments suggest that 14% of the total fission cross section is associated with the fission of a targetlike nucleus.
