    INVESTIGATING THE ISOTOPIC EFFECTS IN NUCLEAR FRAGMENTATION
    (POLISH ACAD SCIENCES INST PHYSICS, 2011) Buyukcizmeci, N.; Bulut, F.; Erdogan, M.; Imal, H.; Ogul, R.; Botvina, A. S.; Mishustin, I. N.
    Modifications for symmetry energy coefficients of nuclear matter at freeze-out density are investigated on the basis of the Statistical Multifragmentation Model (SMM). In order to compare our predictions with MSU experimental data we consider the fragmentation of the projectiles (124)Sn and (112)Sn which were also used for the MSU experiments, and of the projectiles (124)Sn La and (107)Sn used for the ALADIN experiments. Comparing our results with the experimental data, it is confirmed that a significant reduction of the symmetry term coefficient is found necessary to reproduce the mean < N >/Z values of light fragments.

    Surface and symmetry energies in isoscaling for multifragmentation reactions
    (IOP PUBLISHING LTD, 2009) Ogul, R.; Atav, U.; Bulut, F.; Buyukcizmeci, N.; Erdogan, M.; Imal, H.; Botvina, A. S.
    The possibilities of modifications for symmetry and surface energy coefficients of nuclear matter at freeze-out density are investigated theoretically by means of isoscaling (isotopic scaling) on the basis of a statistical multifragmentation model. It is seen that while the isoscaling parameters as predicted by Markov chain calculations for the single sources (124)Sn and (112)Sn are very sensitive to the symmetry term, the surface energy variation slightly affects the isoscaling parameters in the multifragmentation region. The influence of these changes on the mean neutron to proton ratios of light fragments for 2 <= Z <= 10 is also shown. Comparing our results with MSU experimental data, it is confirmed that a significant reduction of the symmetry-term coefficient is found necessary to reproduce the isoscaling parameters of Z <= 8 fragments.
