“…In literature, several experimental as well as theoretical attempts have been made to explore the effect of incident beam energy, collision geometry and mass of the reacting partners on the fragmentation pattern [1][2][3][4]. In recent studies, Puri and co-workers found rise and fall of the multiplicity of intermediate mass fragments (IMFs) in accordance with experimental observations [5,6].…”

We study the role of systematic reduction and enhancement in nuclear radius on the multiplicities of various fragments using the Isospindependent Quantum Molecular Dynamics (IQMD) model. We find that multiplicities of various fragments are sensitive towards change in nuclear radius. We also find that peak center-of-mass energy (E max cm ) and peak multiplicity of intermediate mass fragments ( N IMF max ) are sensitive towards the nuclear radius.

“…However, in recent times many effective and proficient, algorithms are also available in the literature. The quantum molecular dynamics(QMD) generated phase space analysed through one such algorithm simulated annealing clusterization algorithm (SACA) [29] tends to solve the long standing problem of QMD method. The reactions are followed until the elliptical flow saturates i.e.…”

The effect of density dependent symmetry energy is studied on elliptical flow is studied using isospin-dependent quantum molecular dynamics model(IQMD). We have used the reduced isospindependent cross-section with hard(H) equation of state to study the sensitivity of elliptical flow towards symmetry energy in the energy range of 50 -1000 MeV/nucleon. The elliptical flow becomes zero at a particular energy termed as transition energy. A systematic effort has been made to pin down the transition energy for the density dependent symmetry energy. 25.75.Ld Recently, an attempt was made by S. Kumar el. al. [9] to correlate the elliptical flow with isospin content of a reaction. Various studies [9,13] concluded the elliptical flow as a powerful probe for the symmetry energy. Unfortunately, all the calculations were silent about the den- PACS

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.
