Öğe Investigation of isotope composition of nuclear fragments with angular momentum and Coulomb effects in peripheral Kr-84+Sn-112,Sn-124 collisons at 35 A MeV(SPRINGER SINGAPORE PTE LTD, 2015) Buyukcizmeci, Nihal; Ergun, Aysegul; Imal, Hamide; Ogul, Riza; Botvina, Alexander S.New theoretical calculations are performed to investigate the Coulomb proximity and angular momentum effects on multifragmentation picture for Kr-84+Sn-112,Sn-124 collisions at an incident beam energy of 35 MeV/nucleon. Charge and isotopic distributions and the mean neutron-to-proton ratios of the fragments are reproduced within the microcanonical Markov chain calculations on the basis of Statistical Multifragmentation Model. It is shown that the Coulomb interactions and angular momentum effects are very important to reproduce isotopic composition of nuclear fragments in peripheral heavy-ion collisions at Fermi energies. Our results imply that it is possible to investigate in laboratories the modification of structure parameters of fragments, such as the symmetry energy coefficient, at subnuclear densities in dense environment of other species.
