Abstract

We study the threshold excitation of metastable He^*(1s2s ^1,3S) states by combined electron impact and intense laser radiation (λ 532 nm/1064 nm, I 10¹⁰-10¹²W/cm²). A new experimental setup is used combining a ns-pulsed electron beam extracted from a photo-cathode, a single frequency Nd:YAG laser beam and a reaction microscope. Fully differential scattering cross sections are obtained by measuring the recoil momentum of the metastables.
