    "abstract": "We present a simple method for obtaining elastic scattering phase shifts and\ncross sections from energies of atoms or ions in cavities. This method does not\nrequire calculations of wavefunctions of continuum states, is very general, and\nis extremely convenient from practical point of view: some conventional\ncomputer codes designed for the energies of bound states can be used without\nmodifications. The application of the method is illustrated on an example of\nelectron scattering from Kr and Ar. From Brueckner orbital energies in variable\ncavities, we have obtained ab initio cross sections that are in close agreement\nwith experiment. The relativistic effects are also considered and found to be\nsmall below 10 eV.",
