| Description: |
An accurate Fortran code for computing hydrogenic continuum wave functions at a wide range of parameters. The accurate computations of hydrogenic continuum wave functions are very important in many branches of physics such as electron-atom collisions, cold atom physics, and atomic ionization in strong laser fields, etc. Although there already exist various algorithms and codes, most of them are only reliable in a certain ranges of parameters. In some practical applications, accurate continuum wave functions need to be calculated at extremely low energies, large radial distances and/or large angular momentum number. Here we provide such a code, which can generate accurate hydrogenic continuum wave functions and corresponding Coulomb phase shifts at a wide range of parameters. Without any essential restrict to angular momentum number, the present code is able to give reliable results at the electron energy range \([10^{- 3},10^{3}]\) eV for radial distances of \([10^{ - 2},10^{4}]\) a.u. We also find the present code is very efficient, which should find numerous applications in many fields such as strong field physics. |
