Abstract
There exists an intriguing problem when bosonic clusters as bound states of fermions are produced in the reaction, and the Bose character of the composite clusters competes with the fermionic properties of their constituents. In the analysis of 40 Ca + 40 Ca reactions at 35MeV/A we selected classes of projectile-like sources with exit channels consisting of only bosons, only fermions, only even-even nuclei, only odd - odd nuclei, only even - odd nuclei and only alpha-conjugate nuclei, respectively and searched for kinematic characteristics of these systems which might differ depending upon the type of matter selected. The distributions of various observables for the different classes of matter and comparisons between them will be presented and discussed.
Highlights
The study of systems composed of mixtures of bosons and fermions stimulates significant theoretical and experimental efforts in different fields of physics
In this paper we study the projectile-like sources of different composition and compare the results to the Antissymmetrized Molecular Dynamics Model (AMD) [6] [7] incorporating a statistical decay code GEMINI [8] as a afterburner
It has been known that fluctuations are large for statistical systems near their critical points, the study of multiplicity fluctuations of hadrons produced in high-energy heavy-ion collisions is of importance to study the phase transition [11] [12] [13] [14]
Summary
The study of systems composed of mixtures of bosons and fermions stimulates significant theoretical and experimental efforts in different fields of physics. Atomic nuclei are commonly described as systems of strongly interacting fermions, namely neutrons and protons. In experiments we observe the existence of phenomena that can be explained by considering nuclei as systems composed of bosonic clusters, the most common being α particles. That in heavy ion collisions the produced particles do not follow classical statistics [1] because of the quantum nature, the correct distribution function must be used in the calculations. In this paper we study the projectile-like sources of different composition and compare the results to the Antissymmetrized Molecular Dynamics Model (AMD) [6] [7] incorporating a statistical decay code GEMINI [8] as a afterburner
