Fragmentation processes in nuclear reactions

Inclusive and exclusive measurements in the projectile breakup of 7Li

“…where Ú denotes the projectile velocity [5]. In this calculation for the breakup of Li, a value of 100 MeV.fm ¿ ¾ has been used for ¼ .…”

“…The energy integrated triple differential cross sections for alpha particles extracted at each angle are shown in figure 2. These cross sections were compared with the direct fragmentation model (DFM) of breakup reactions formulated within the post-form DWBA [5]. In this model the incoming projectile is assumed to breakup instantaneously in the Coulomb and nuclear fields of the target nucleus.…”

“…where is the three-body density of states [5]. The optical potentials needed for the calculations are taken from the literature.…”

“…A realistic approach is the DWBA breakup theory developed by Baur and coworkers. The theory is based on a one-step breakup mechanism and enables calculations of contributions from both the elastic and inelastic breakup modes [5].…”

Theory of the Trojan–Horse method

“…The observation of a similarity between cross sections for two-body and closely related three-body reactions under certain kinematical conditions [15] led to the introduction of the Trojan-Horse method (THM) [16], see also [17,18]. The aim of the THM is to extract the cross section of an astrophysically relevant two-body reaction…”
