A check for consistency between positron-atomic hydrogen total,positronium formation,and ionization cross section measurements

We have recently measured total cross sections for 5 to 302 eV positrons scattered by atomic hydrogen using a beam transmission technique. A check for consistency is made between these measurements and prior measurements of positronium formation and ionization cross sections by making use of available theoretical calculations of elastic and excitation cross sections for positron-atomic hydrogen scattering.
