Abstract:

This paper reports the measurements of valence electron structure for the iso-butane (iso-C4H10) using high resolution (ΔE = 0. 9eV FWHM, Δp = 0.1a. u) (e, 2e) spectrometer. The impact energy was 1200 eV plus binding energy (i. e. 1205 to 1230 eV) and symmetric non-coplanar kinematics was employed. The experimental momentum Profiles have been compared with those calculated using Hartree -Fock method and Density Function Theory.

Key words: Iso-butane, Binding energy spectra, Momentum profiles
