NucD/DFS [ Subroutines ]

[ Top ] [ NucD ] [ Subroutines ]

NAME

subroutine DFS(A,Z,r,a,rho,rms,rchrg)

PURPOSE

Proton/Neutron Density Parameters from Skyrme Systematics Fermi Shape are used with half-density radius and diffuseness:

NOTES

  • R_{q}=R_{0q}*A^(1/3)+R_{1q}+R_{2q}*AS
  • a_{q}=a_{0q} +a_{1q}*AS

A=Mass Number, AS=(N-Z)/A Asymmetry, \tau=1,2 for p,n

Convention:

  • Protons: q = 1,
  • Neutrons: q = 2,
  • weighted Average: q = 3, with e.g. R_av=(N*R_n+Z*R_p)/A

etc.

INPUTS

  • integer, intent(in) :: A ! Mass number of nucleus
  • integer, intent(in) :: Z ! Charge

OUTPUT

  • real, dimension(1:3),intent(out) :: r -- radii
  • real, dimension(1:3),intent(out) :: a -- surface parameter
  • real, dimension(1:3),intent(out) :: rho -- contains the central densities (from normalization to Z/N numbers)
  • real, dimension(1:3),intent(out),optional :: RMS -- contains the mass rms-radii (obtained analytically)
  • real, dimension(1:3),intent(out),optional :: RCHRG -- contains the charge rms-radii (obtained analytically)

Convention for indices:

  • i=1: Protons
  • i=2: Neutrons
  • i=3: weighted Average with e.g. R_av=(N*R_n+Z*R_p)/A


NucD/nuclfit [ Subroutines ]

[ Top ] [ NucD ] [ Subroutines ]

NAME

subroutine nuclfit(ma,mz,mradi,msurf,mdens)

PURPOSE

Evaluates basic properties of a nucleus

INPUTS

RESULT

  • real mradi :: nuclear radius
  • real msurf :: nuclear surface parameter
  • real mdens :: nuclear maximal density
