Abstract
Experimentally determined electron drift velocities are fitted directly with a three-parameter modified effective range theory (MERT) representation of the S-wave phaseshift together with fixed values of the much smaller P- and D-wave phaseshifts calculated from the MERT formulae representing the phaseshifts derived from other sources. The result is an improved value of the e-Ne scattering length of (0.214+or-0.005) a0, and phaseshifts from zero to above 2 eV. Comparisons are made with other phaseshifts and momentum-transfer, total and differential cross sections.Keywords
