We study the yields and the momentum distributions of projectile-like fragments from peripheral collisions of 64Ni (25 MeV/nucleon) on 64Ni. The experimental data were obtained in previous works with the BigSol separator system at the Cyclotron Institute of Texas A&M University. Projectile fragments were collected and analyzed at forward angles (1.5°-3.0°). The production cross sections and the momentum distributions (p/A) of the fragments were systematically studied and compared with the Deep-Inelastic Transfer (DIT) model and the Constrained Molecular Dynamics (CoMD) model followed by the deexcitation model GEMINI. Special attention is given to the possibility to produce neutron-rich rare isotopes of elements at the beginning of the astrophysical r-process. Moreover, efforts to reconstuct the excitation energy distributions are ongoing in hopes to shed light to the reaction mechanisms of peripheral collisions at this energy (25 MeV/nucleon).
