“…Recently, the CHIC Collaboration [9] measured the yields of d/p and t/p in asymmetric collisions of p + Kr, O + Kr, and Ne + Ar. The statistical evaporation models were reported to fail to reproduce these ratios [9]. The microscopic and mean-field calculations, on the other hand, could explain the data nicely.…”

We report our analysis of d like /p like ratio and entropy production in heavy-ion collisions using an isospindependent quantum molecular dynamics model. The entropy is estimated using the method proposed by Siemens and Kapusta [P. J. Siemens and J. I. Kapusta, Phys. Rev. Lett. 43, 1486(1979]. Our calculations are in good agreement with experimental data. We also study the role of the neutron content of colliding pairs on the production of d like /p like ratio and entropy. Our findings reveal that entropy decreases with an increase in the isospin asymmetry for both isotopic and isobaric pairs.

“…Such behavior is believed to be resulted from the coalescence production mechanism [6,7]. Experimentally, the study of d/p ratios obtained in asymmetric collisions of p+Kr, O+Kr, and Ne+Ar also indicates the importance of coalescence mechanism [8]. In this study, it was observed that d/p ratio increases with the beam energy.…”

The entropy production in medium energy heavy-ion collisions is analyzed in terms of ratio of deuteronlike to protonlike clusters (d like /p like ) using quantum molecular dynamics (QMD) model.The yield ratios of deuteronlike-to-protonlike clusters calculated as a function of participant proton multiplicity closely agree with experimental trends. Our model predictions indicate that full thermodynamical equilibrium may not be there even for the central geometry. The apparent entropy extracted from the yield ratios of deuteronlike-to-protonlike clusters, however, reflects the universality characteristics i.e. it is governed by the volume of reaction independent of the target-projectile combination. Our calculations for apparent entropy produced in central collisions of Ca+Ca and Nb+Nb at different bombarding energies are in good agreement with 4π Plastic Ball data.

“…The property of preserving the early traces and unaltered behavior in the expansion phase of compressed state of nuclear matter gives one the obvious reason to study entropy as a crucial parameter. Various valuable theoretical and experimental attempts have been done in the past to study the entropy production [18][19][20][21][22][23][24][25][26]. For example, Doss et al [21] measured the yield ratios for lighter fragments and entropy for the reactions of 40 Ca+ 40 Ca and 93 Nb+ 93 Nb at incident energies of 400 and 600MeV/nucleon, respectively.…”

We demonstrate the role of mass asymmetry on composite yield of light mass particles and entropy production by analyzing the reactions with various mass asymmetries throughout the periodic table. The study is conducted using various mass asymmetries via keeping the total system masses constant to 40, 80, 160 and 240 units. The study is done at different incident energies of 400, 600, 800 and 1000 MeV/nucleon. We found that, though, the production of composite yield to calculate entropy production changes for different asymmetries of colliding partners but the entropy production remains almost constant for all mass asymmetries as well as system masses.
