Energy deposition mechanisms for electrons colliding with F2 and F2 mixtures

is report rev-lews the potentially i-portant nechanisrjs and ih-s avail.'iMu3ata :'or energy deposition by electrons colliding with targets consisting of r ar;d •".r.ixtures.Since the target composition is a variable outside the £copo cf this review, very little discussicn or data rill be presented for species other than F.. Fortunately, secondary-literature sources have con densed r.uzh of the available data for r:ost of the cordon ^as additives, ".any or these secondary literature sources will be discussed.As F ? has received relatively little attention in the literature, the electronic structure cf the F : , -, and F-systems is considered in detail.Available electron scattering •Jata and some new inferences based on photon scattering information are presented The :i tor * tare search on which this work is based was terminated :-ay i t I97h-I NOT PCI ipcnwrrJ h> IV United ^uiri (putrttirmnt, Nrrilin ;?*c VmUi Suin mf (br (*4/tat Stlfrt Alo&k twn C<*nniuhjD.Jew Uf ujrutitt, **$mi*jr u+ci .^DfHumnui)IrrfJ Ujtttit* PT mpoftubiltfr fut (he attufjcjr, cok^ p^uJiKl uf pi-ut*n duclin*J v 4*f ttprntat% I hit it* w *VuJJ mil tnfliOiJ pfirdcrr o^nrJfvhl*.fron ftei\ U6 is shown by , rim Sefs, Vf, Uz by -, and from P.eC.50 by the energy Iocs per ion pair.Hence, seme but not all data required to start a "chemical code" is available from this program.In addition* there are a number of approximate features in the treatment, such a fl the "continuous slowdown approximation/' wtnsa lind-aticns ahould be understood.Undoubtedly, many other prcgra-s oV potential use are available or are being developed.This ^abject goes beyond the scope of this report.g-T ["• -_•-.PT"-^T _-
