“…In [11,15] we have shown that the surface term coefficient increases slightly with decreasing N/Z of the fragments, and the symmetry energy coefficient for primary hot fragments at the low-density freeze-out is significantly reduced. Finally, besides the existing and recent calculations [12,[17][18][19], the present results for isoscaling give additional confidence to the statistical multifragmentation model.…”

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.

“…The mass and charge distributions at various excitation energies exhibit very different and interesting behavior. In our previous paper [10], we demonstrated that the evolution of the mass yield distribution is determined by the excitation energy. In the excitation energy range for E * ≤ 1 MeV per nucleon, one may observe fission-like distributions, while in the region of 1-3 MeV per nucleon an inverted U-shaped distribution is observed.…”

Abstract. Charge distributions of the fragments emitted from the disintegration of uranium isotopes 235 U and 238 U at various excitation energies up to 10 MeV per nucleon were investigated on the basis of a statistical approach. The calculations reproduce the fundamental properties of the fission at low excitation energies for E * ≤ 0.5 MeV/A. The variation of the average value of the maximal charge, < Zmax >, of the emitted fragments with excitation energy is determined.
