Quasifree scattering of the loosely bound nucleons in the radioactive beam experiments

An alternative mechanism of neutron formation is considered: 'shaking off' the loosely bound nucleon from from the projectile with its subsequent scattering on a target. The collision may be the central one and the projectile's core may simply fuse with the target nucleus (at low and medium energies) and will be not detected in exit channel. All outermost nucleons of the projectile (e.g., 4 for 8 He)may participate in such the process. In this case their strong focusing occurs behind the target nucleus and the high-density neutron matter is formed
