We present our recent study of cross sections and angular distributions ofprojectile fragments from heavy-ion reactions at beam energy of 15 MeV/nucleon.We studied the production cross sections and the angular distributions ofneutron-rich nuclides from collisions of a 86 Kr (15 MeV/nucleon) beam withheavy targets ( 64 Ni, 124 Sn and 238 U). Experimental data from our previouswork at Texas A & M were compared with model calculations. Our calculationswere based on a two-step approach: the dynamical stage of the collision wasdescribed with, first, the phenomenological Deep-Inelastic Transfer model (DIT)and, alternatively, with the microscopic Constrained Molecular Dynamics model(CoMD). The de-excitation of the hot heavy projectile fragments was performedwith the Statistical Multifragmentation Model (SMM). An overall gooddiscription of the available data was obtained with the models employed.Furthermore, we performed calculations with a radioactive beam of 92 Kr (15MeV/nucleon) interacting with a target of 238 U. We observed that themultinucleon transfer mechanism leads to extremely neutron-rich nuclides towardand beyond the astrophysical r-process path.
