NAME

NAMELIST /pn_medium/

PURPOSE

Includes the input switches:

[ Top ] [ pn_medium_width ] [ Global module-variables ]

SOURCE

  logical, save :: debug=.false.

PURPOSE

If .true. debug infos are produced, if .false. not..


pn_medium_width/density_dependent [ Global module-variables ]

[ Top ] [ pn_medium_width ] [ Global module-variables ]

SOURCE

  logical, save :: density_dependent=.false.

PURPOSE

the density of the spectral function


pn_medium_width/form_factor [ Global module-variables ]

[ Top ] [ pn_medium_width ] [ Global module-variables ]

SOURCE

  logical, save :: form_factor=.true.

PURPOSE

If .true. the form factor for the width is used


pn_medium_width/pn_medium_switch [ Global module-variables ]

[ Top ] [ pn_medium_width ] [ Global module-variables ]

SOURCE

  logical, save :: pn_medium_switch=.true.

PURPOSE

If .true. medium_modifications will be used


pn_medium_width/readinput [ Subroutines ]

[ Top ] [ pn_medium_width ] [ Subroutines ]

NAME

subroutine readinput

PURPOSE

This subroutine reads out the jobcard "pn_medium" which may contain:

Only called once to initialize the module.


pn_medium_width/proton_width_medium [ Functions ]

[ Top ] [ pn_medium_width ] [ Functions ]

NAME

real function proton_width_medium(momLRF,pdens,ndens,mu_extern)

PURPOSE

function for calculation of the proton width in a medium

INPUTS

  • real, dimension(0:3) :: momLRF -- momentum of resonance in LRF
  • real :: pdens -- proton density [fm^{-3}]
  • real :: ndens -- neutron density [fm^{-3}]
  • real, OPTIONAL :: mu_extern -- needed for density dependent width

pn_medium_width/proton_width_mdd [ Functions ]

[ Top ] [ pn_medium_width ] [ Functions ]

NAME

real function proton_width_mdd(momLRF,pdens,ndens,mu_extern)

PURPOSE

function for calculation of the proton width in a medium. Reads out data file and uses a spline with it.

INPUTS

  • real, dimension(0:3) :: momLRF -- momentum of resonance in LRF
  • real :: pdens -- proton density [fm^{-3}]
  • real :: ndens -- neutron density [fm^{-3}]
  • real, OPTIONAL :: mu_external -- needed for density dependent width

NOTES

It uses the data input files /baryon/0*.34 right now only for z/a =0.5
