Broadband photon yield of Kr excited by monoenergetic electron impact. Part II: 12–15 eV

Abstract

The broadband photon yield in the spectral range 165–650 nm of Kr excited by monoenergetic electrons with energies from 12 to 15 eV has been measured. Several negative-ion states are observed both below and above the 2P3/2 ionization threshold. No structures are detected above the 2P1/2 limit, even with a total accumulation of 200 million counts per observation point.
