✦ Synopsis

Total absolute cross sections for electron SF, scattering have been measured in the 75-4000 eV energy range. The data have been fitted with a Born-like formula. A comparison with other experimental data and partial cross sections is presented.

1. introduction

The SF, molecule has received much attention in recent years. Measurements have been performed with probably all available spectroscopies to elucidate the molecular structure, electronic, vibrational and rotational levels, and interaction mechanisms of this molecule with laser, ion and electron beams. Part of this interest has been triggered by the similarity of this molecule with the UFs molecule which is important for uranium isotope separation. The SF, has been considered an easily obtainable substitute for UFs. And the SF6 molecule has been used for a long time in high-voltage gas insulation and related technologies. The peculiar structure of this molecule has promoted theoretical and experimental work. In the field of electron collisions, total electron scattering cross sections exist in the energy range from less than 0.05 to 700 eV [ 1-5 1. Differential electron SF6 cross sections have been measured by Srivastava et al. [ 61 and Sakae et al. [ 71. Ionization cross sections have been measured by Rapp and Englander-Golden [ 8 ] and more recently by Margreiter et al. [ 91. Sta6ski and Adamczyk [lo] have measured relative ionization cross sections. Dehmer et al. [ 111 have performed theoretical calculations of the e--SF6 total
