Further evidence for a stiff nuclear equation of state from a transverse-momentum analysis of Ar(1800 MeV/nucleon) + KCl.

چکیده
The novel momentum analysis technique introduced by Danielewicz and Odyniec can be used to detect and exhibit collective flow in the light System Ar(1800 MeV/nucleon) + KC1 where the usual kinetic energy flow analysis fails. The microscopic Vlasov-Uehling-Uhlenbeck theory which includes the nuclear mean field, two-body collisions, and Pauli blocking is used to study this phenomenon. The resulting transverse momentum transfers turn out to be quite sensitive to the nuclear equation of state. From a comparison with experimental data, evidence is presented for a rather stiff nuclear equation of state. The cascade model is unable to describe the data.

Excitation function of nucleon and pion elliptic flow in relativistic heavy-ion collisions
Within a relativistic transport (ART) model for heavy-ion collisions, we show that the recently observed characteristic change from out-of-plane to in-plane elliptic flow of protons in mid-central Au+Au collisions as the incident energy increases is consistent with the calculated results using a stiff nuclear equation of state (K= 380 MeV). We have also studied the elliptical flow of pions and ...
متن کاملElliptic flow in heavy ion collisions near the balance energy
The proton elliptic flow in collisions of Ca on Ca at energies from 30 to 100 MeV/nucleon is studied in an isospin-dependent transport model. With increasing incident energy, the elliptic flow shows a transition from positive to negative flow. Its magnitude depends on both the nuclear equation of state (EOS) and the nucleon-nucleon scattering cross section. Different elliptic flows are obtained...

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done...
متن کاملDisappearance of Transverse Flow in Central Collisions for Heavier Nuclei
Using the Quantum Molecular Dynamics model, we analyze the disappearance of flow in heavier colliding nuclei. A power law mass dependence (∝ 1 √ A ) is obtained in all cases. Our results are in excellent agreement with experimental data which allows us to predict the balance energy for U + U collision around 37-39 MeV/nucleon. Thirty years ago it was predicted by Scheid and Greiner [1] that in ...
متن کاملEquation of State and Nucleon-Nucleon Cross Section in Medium
The equation of State (EOS) and nucleon-nucleon (NN) cross section in medium have been studied, using the antisymmetrized molecular dynamics model (AMD-V) of Ono et al. [1]. The model has been successfully applied to the Zn + Ni reaction at 35A to 79A MeV [2]. In the previous analysis in reference [2] the Gogny force and an empirical NN cross section were used to reproduce the experimental resu...
