    Allan, Michael ; May, Olivier ; Fedor, Juraj ; Ibǎnescu, Bogdan C ; Andrić, Lidija ; Winstead, Carl ; McKoy, Vincent

    In: Journal of Physics: Conference Series, 2012, vol. 388, no. 5, p. 052082

    We present absolute experimental cross sections for elastic scattering, vibrational excitation by electron impact and for dissociative electron attachment to 1,3-butadiyne, as well as calculations of the elastic cross sections.

    Resonance effects in elastic cross sections for electron scattering on pyrimidine: Experiment and theory

    Regeta, Khrystyna ; Allan, Michael ; Winstead, Carl ; McKoy, Vincent ; Mašín, Zdeněk ; Gorfinkiel, Jimena D.

    In: The Journal of Chemical Physics, 2016, vol. 144, no. 2, p. 024301

    We measured differential cross sections for elastic (rotationally integrated) electron scattering on pyrimidine, both as a function of angle up to 180∘ at electron energies of 1, 5, 10, and 20 eV and as a function of electron energy in the range 0.1–14 eV. The experimental results are compared to the results of the fixed-nuclei Schwinger variational and R-matrix theoretical methods, which...
