Effects of geometric constraints on the nuclear multifragmentation process
(2007) [Artigo de periódico]We include in statistical model calculations the facts that in the nuclear multifragmentation process the fragments are produced within a given volume and have a finite size. The corrections associated with these constraints ... -
Finite-size effects in isobaric ratios
(2012) [Artigo de periódico]The properties of isobaric ratios, between nuclei produced in the same reaction, are investigated using the canonical and grand-canonical statistical ensembles. Although the grand-canonical formulas furnish a means to ... -
Influence of secondary decay on odd-even staggering of fragment cross sections
(2013) [Artigo de periódico]Odd-even staggering (OES) appears inmany areas of nuclear physics and is generally associated with the pairing term in the nuclear binding energy. To explore this effect, we use the improved statistical multifragmentation ... -
Influence of the density of states on the odd-even staggering in the charge distribution of the emitted fragments in nuclear heavy-ion collisions
(2014) [Artigo de periódico]The fragmentation of thermalized sources is studied using a version of the Statistical MultifragmentationModel which employs state densities that take the pairing gap in the nuclear levels into account. Attention is focused ... -
Internal and kinetic temperatures of fragments in the framework of a nuclear statistical multifragmentation model
(2015) [Artigo de periódico]The agreement between the fragments’ internal and kinetic temperatures with the breakup temperature is investigated using a statistical multifragmentation model, whichmakes no a priori assumption on the relationship between ... -
Isospin effects and the density dependence of the nuclear symmetry energy
(2009) [Artigo de periódico]The density dependence of the nuclear symmetry energy is inspected using the statistical multifragmentation model with Skyrme effective interactions. The model consistently considers the expansion of the fragments' volumes ... -
Probing the symmetry energy from the nuclear isoscaling
(2008) [Artigo de periódico]Using different parametrizations of the nuclear mass formula, we study the sensitivity of the isoscaling parameters to the mass formula employed in grand-canonical calculations. Previous works on isoscaling have suggested ... -
Statistical multifragmentation model with discretized energy and the generalized Fermi breakup : formulation of the model
(2013) [Artigo de periódico]The generalized Fermi breakup model, recently demonstrated to be formally equivalent to the statistical multifragmentation model, if the contribution of excited states is included in the state densities of the former, is ... -
Statistical multifragmentation model with Skyrme effective interactions
(2009) [Artigo de periódico]The statistical multifragmentation model is modified to incorporate the Helmholtz free energies calculated in the finite temperature Thomas-Fermi approximation using Skyrme effective interactions. In this formulation, the ... -
Temperature effects in nuclear isoscaling
(2009) [Artigo de periódico]The properties of the nuclear isoscaling at finite temperature are investigated and the extent to which its parameter α holds information on the symmetry energy is examined. We show that, although finite temperature effects ...
