Characteristics of the fragments produced in central collisions of129Xe+natSnfrom 32Ato 50AMeV

Abstract: Characteristics of the primary fragments produced in central collisions of129 Xe + nat Sn from 32 to 50 AMeV have been obtained. By using the correlation technique for the relative velocity between light charged particles (LCP) and fragments, we were able to extract the multiplicities and average kinetic energy of secondary evaporated LCP. We then reconstructed the size and excitation energy of the primary fragments. For each bombarding energy a constant value of the excitation energy per nucleon over the whol… Show more

“…Reconstruction of primary fragments could provide a better understanding. Correlation techniques may provide a powerful tool for primary fragment reconstruction [2,27]. A small dependence on E ⋆ is observed for any mass range (except for C Although the output values are still higher than the expected values, they present a behavior similar to the one observed for primary fragments and appear to be only shifted by a constant offset.…”

“…The question we want to address in this paper is the underlying mechanisms responsible for these threefragment events: are they the result of deeply-inelastic reactions (followed by fission of one of the two partners, or with the third fragment resulting from a neck formed between projectile and target), or do they result from the decay of a composite system (not necessarily fullyequilibrated) ? Is the break-up a sequential continuation of low-energy fission processes to higher available energies, or is it a precursor of the simultaneous nuclear disassembly (multifragmentation) observed at higher energies for this same system [14,15]?…”
