Density and Temperature of Compressed Nuclear Matter

STUDY OF NUCLEAR LEVEL DENSITY AND SPIN CUT-OFF FACTORS

Nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹A‹63,from a microscopic theory, which includes nuclear pairing interaction. Single particle levels for both Seeger and Nilsson potentials were used in the calcdations. Level densities extracted from the theory are compared with their conesponding experimental values, It is found that the overall...

Gluon condensation and deconfinement critical density in nuclear matter

The critical density for the transition to the deconfined phase, at zero temperature, has been evaluated by analyzing the behavior of the gluon condensate in nuclear matter. Due to the non linear baryon density effects, the critical density,ρc turns out about nine times the saturation density, ρ0 for the value of the gluon condensate in vacuum < (αs/π)G 2 >= 0.012 GeV . For neutron matter ρc ≃ ...

Landau Ginzburg Theory and Nuclear Matter at Finite Temperature

Based on recent studies of the temperature dependence of the energy and specific heat of liquid nuclear matter, a phase transition is suggested at a temperature ∼ .8 MeV. We apply Landau Ginzburg theory to this transition and determine the behaviour of the energy and specific heat close to the critical temperature in the condensed phase. The existence of an energy gap in the spectrum of even-ev...

Light clusters in nuclear matter of finite temperature

We investigate properties and the distribution of light nuclei (A ≤ 4) in symmetric nuclear matter of finite temperature within a microscopic framework. For this purpose we have solved few-body Alt-Grassberger-Sandhas type equations for quasi-nucleons that include self-energy corrections and Pauli blocking in a systematic way. In a statistical model we find a significant influence in the compos...
