densityStatic/ReAdjust [ Subroutines ]

[ Top ] [ densityStatic ] [ Subroutines ]

NAME

subroutine ReAdjust(nuc, potP, potN, potC)

PURPOSE

This routine recalculates the density distributions for protons and neutrons by considering the given potentials as static and fulfill the condition

   sqrt(p_F^2+m_N^2) + U - m_N == E_sep ~ -8MeV

With the Local-Thomas-Fermi, we connect the resulting fermi momentum to a density,

   rho = p_F^3/(3pi^2)

Since the potentials are given as function of r, we calculate rho(r).

Thus, given proton and nucleon baryon potential (for fixed momentum) and the coulomb potential, the parametrization of the nuclear density is readjusted.

This routine is called by baryonPotentialModule/HandPotentialToDensityStatic

INPUTS

  • type(tNucleus),pointer :: nuc -- the nucleus to consider
  • real, dimension(0:) :: potP, potN -- the proton,neutron potentials with p=pF. The dimension has to be identical to nuc%densTab(0: ,1:2).
  • real, dimension(0:) :: potC -- The Coulomb potential (>0, in GeV)

OUTPUT

  • nuc%densTab(0: ,1:2) is changed
