Isospin dependent multi - fragmentation in 112 Sn + 112 Sn and 124 Sn + 124 Sn collisions
نویسنده
چکیده
Significant differences in the relationships between fragment, neutron, and charged particle multiplicities were found between Sn+Sn and Sn+Sn collisions at 40 MeV/A. In this paper we explore the possibility to explain this phenomenon in the framework of percolation models, and find, that the results are only reproducible in part.

Isospin dependent multifragmentation in 112 Sn 1 112 Sn and 124 Sn 1 124 Sn collisions
Percolation models have proven highly successful in the simulation of multifragmentation reactions in the past @1,2#. Within these models, fragmentation is described by first distributing a set of points or sites, each representing a nucleon, on a three-dimensional lattice, which represents the bonds between the sites. In the case of a simple rectangular lattice, each site is connected to six n...
متن کاملMultifragment Production in Reactions of 112 Sn 1 112 Sn and 124 Sn 1 124 Sn at E y A 5 40 MeV
Multiplicities of intermediate-mass fragments (IMFs), neutrons, and charged particles were measured for 112Sn 1 112Sn and 124Sn 1 124Sn at EyA 40 MeV. Significantly different scalings of the mean IMF multiplicities with neutron and charged-particle multiplicities are observed for the two reactions. These differences can be qualitatively understood in terms of fragment emission from an expandi...
متن کاملEffect of nucleon exchange on projectile multifragmentation in the reactions of 28 Si + 112 Sn and 124 Sn at 30 and 50 MeV / nucleon
Multifragmentation of quasiprojectiles was studied in reactions of Si beam with Sn and Sn targets at projectile energies 30 and 50 MeV/nucleon. The quasiprojectile observables were reconstructed using isotopically identified charged particles with Zf ≤ 5 detected at forward angles. The nucleon exchange between projectile and target was investigated using isospin and excitation energy of reconst...

Single-particle kinetic energy spectra and two-particle small angle correlations of protons (p), deuterons (d) and tritons (t) have been measured simultaneously in 61A MeV Ar + Al, Sn and Sn collisions. Characteristics of the emission sources have been derived from a “source identification plot” (βsource–ECM plot), constructed from the single-particle invariant spectra, and compared to the comp...
