Momentum peak shift and width of longitudinal momentum distribution of projectilelike fragments produced at E=290MeV/nucleon

Anisotropic momentum distribution of 11B and 11C produced from 12C beam at 100 MeV/nucleon

“…In measurements of the angular distribution with Tb target, there is a lack of data at 0 mrad. More details of the experimental technique to observe momentum distributions have been previously reported [16,19]. The P L resolution determined from that for TOF measured with the primary beam (0.16 ns), is 8 MeV/ c, and is smaller than that corresponding to the momentum acceptance of SB2, ΔP ∼ 50 MeV/c.…”

“…However, the accuracy of observed data is insufficient for quantitative discussions on the contribution of Coulomb scattering. In the P L distribution, a tail structure has been universally observed on the low-P L side [17][18][19]. A nucleon-exchange reaction between the target and projectile [18,20] has been suggested to explain the low-P L tail, and the asymmetric-Gaussian function is applied to examine the systematic behavior of the low-P L tail.…”
