Design of a CO₂gasdynamic laser with selective thermal excitation and an unstable resonator

Abstract

The dependence of the Hornbeck-Molnar ionisation cross section on the relative kinetic energy of the colliding partners He(53P2)+He has been measured for the first time over the 0.015-0.40 eV range (1200-6000 m s-') in a crossed-beam experiment using a time-of-flight technique. The 53P level is obtained by optical excitation of the z3S
