Abstract:
A crossed beam experiment is carried out to measure the energy of electrons
emitted in Penning ionization processes by Ne*(3P2,0)–Kr
collisions. The electron energy spectra have been measured at four different
collision energies: 0.050, 0.140, 0.190, 0.460 eV. The analysis of the
results allows the separation of spin orbit contributions both in the
entrance and in the exit channels providing the related cross-section
ratios. Some theoretical considerations have been made to clarify nature and
role of interatomic potentials driving the collisions and some general
features about the role of atomic fine structure in the Penning ionization
processes.
