Elastic and absorption electron collisions with acetaldehyde

We report a theoretical–experimental investigation on elastic electron scattering by acetaldehyde (CH $$_3$$ CHO) in the 0.5–800 eV energy range. Theoretically, Padé approximation and single-center partial-wave expansion method were applied to solve Lippmann–Schwinger equation, whereas molecular complex optical potential was used describe electron–molecule interaction. Calculations independent-atom framework also performed. Angular distributions of elastically scattered electrons measured 10 $$^{\circ }$$ –130 30–800 ranges using crossed beams geometry. Absolute values differential cross sections derived relative flow technique. In addition, integral momentum transfer obtained from experimental theoretical via numerical integration procedure. Comparison between our results previous calculations is made.
