“…At relativistic energies, the reduced width σ 0 is independent of the primary beam energy. At lower energies, the reduction of σ 0 has been observed [33]. The reduction mechanism has been argued by several theoretical works, where the reason is for example due to the Pauli blocking.…”

The reaction mechanism of projectile fragmentation at intermediate energies has been investigated observing the target dependence of the production cross sections of very neutron-rich nuclei. Measurement of longitudinal momentum distributions of projectile-like fragments within a wide range of fragment mass and its charge was performed using a hundred-MeV/n 40 Ar beam incident on Be and Ta targets. By measurement of fragment momentum distribution, a parabolic mass dependence of momentum peak shift was observed in the results of both targets, and a phenomenon of light-fragment acceleration was found only in the Be-target data. The analysis of production cross sections revealed an obvious enhancement of the target dependence except target size effect when the neutron excess is increased. This result implies the breakdown of factorization (BOF) of production cross sections for very neutron-rich nuclei near the drip line.

“…In principle, a lighter target provides higher yields because it contains more target nuclei and results in the emission of fragments at smaller laboratory angles. However a tantalum target was used since its higher neutron excess has been shown [10] to enhance the production of the most neutron-rich fragments.…”

The fact that up to now no coherent picture of the fragmentation mechanism exists in this transitional energy region is reflected by the existence of a large number of theoretical models that have been developed for a quantitative understanding of the fragmentation process [-5-13].…”

Inclusive energy spectra and cross sections of reaction products close to the 14N projectile (11C, 12C, lac, ISN and 150) have been measured in the angular range 0L -1.2~o at an incident energy of 60 MeV/u for five different target nuclei (12C, 27A1, 5SNi, 9~ and 2~ Two components are found to be systematically present in the energy spectra of the carbon isotopes, the first similar to that observed at relativistic energies and the second shifted down in energy characteristic for a very dissipative process. The dependence of the differential and integrated cross sections on the target mass indicates that the two-body final channels (14N, 13C), (14N, 15N) and (14N, 150) are strongly correlated to the fragmentation channels.
