inhomoR

InhomoR is a computer code develop by Jin Lei and Pierre Descouvemont to solve the inhomogeneous equations. We applied three different methods, namely R-matrix method, Green's function method, and Numerov method.

Input description

&global namelist: Ecm,hcm,rmax,lmin,lmax,nr

  • Ecm : Center of mass energy
  • hcm : radial step when using Numerov method.
  • rmax: maximum number of the radial distance
  • lmin: minimum number of partial wave
  • lmax: maximum number of partial wave
  • nr:grid number when using R-matrix method and Green's function method

&systems: massa, massb, za,zb,ja,jb

  • mass,massb : mass numbers of interaction particles
  • za, zb: charge numbers
  • ja,jb: spins

&potential namelist: ptype, a1, a2, rc, uv, av, rv, uw, aw, rw, vsov, rsov, asov, vsow, rsow, asow, vd, avd, rvd, wd, awd, rwd

  • a1, a2, rc, uv, av, rv, uw, aw, rw, vsov, rsov, asov, vsow, rsow, asow, vd, avd, rvd, wd, awd, rwd : potential parameters

  • ptype: defines different types of potential

    1. Woods-Saxon potential.  Potential parameters are defined through the variables: 
       * Volume WS: uv, av, rv, uw, aw, rw
       * Spin-orbit: vsov, rsov, asov, vsow, rsow, asow
       * Surface (derivative) WS: vd, avd, rvd, wd, awd, rwd
    2. Gaussian potential, defined through the parameters: uv,rv,av,uw,rw,aw
