Name

    Subroutine UA638 - Hassitt proton cross sections

Synopsis

      integer*4 nsp, ksp(30), ifail
      real*8    cs(30)
      
      CALL UA638 (nsp, ksp, cs, ifail) 

Arguments

    nsp
    Number of species [in]
    ksp
    List of species code [in]
    cs
    Cross section (see note of subroutine UA630) [out]
    ifail
    Error flag (see diagnostics) [out]

Description

    The subroutine UA637 evaluates the cross sections proposed by Hassitt for collisions between proton and H, He, N2, O2, O., N., H+, He+, O+, NO+, O+2 and electrons. The cross section is expressed in mbarn (10-27cm2) and is evaluated only for components listed in argument ksp.
