The effect of inelastic collisions on the ratio of the longitudinal to lateral diffusion coefficients for electrons in electrostatic fields in gases is investigated for several different momentum transfer cross sections. The effect of varying both the strength of the inelastic effects and their energy dependence is examined and the results are used to discuss some of the DL/f.l data of Wagner et al. (1967).

Blanc's law is exactly applicable when the momentum transfer cross sections for electrons in each constituent of a gas mixture have the same energy dependence in the relevant energy range. This condition is rarely satisfied even for thermal energies. In this paper the magnitude of the errors arising from the applications of Blanc's law is examined for some cases where the condition is strongly violated, and a procedure developed for obtaining useful data from its application even under these circumstances.

Momentum Transfer Range

Differential cross-sections for p-p and p-d elastic scattering have been measured at N. A. L. for 80 < s < 600 GeV 2 in the four-momentum transfer range 0.001 < | t | < 0.15 (GeV/ c ) 2 . Preliminary values are given for the slope parameters in the diffraction region and for the ratio of the real to the imaginary scattering amplitude. The energy dependence of these parameters is discussed.

Mode A

We comment briefly on relations between the elastic and inelastic cross-sections valid for the shadow and reflective modes of the elastic scattering. Those are based on the unitarity arguments. It is shown that the redistribution of the probabilities of the elastic and inelastic interactions (the form of the inelastic overlap function becomes peripheral) under the reflective scattering mode can lead to increasing ratio of [Formula: see text] at the LHC energies. In the shadow scattering mode, the mechanism of this increase is a different one, since the impact parameter dependence of the inelastic interactions probability is central in this mode. A short notice is also given on the slope parameter and the leading contributions to its energy dependence in both modes.
