    Título: Electron-molecule scattering dynamics under the influence of
    multichannel coupling effects

    Resumo:
    The theoretical description of electron-molecule collisions is a
    many-body problem that needs to be approximated in a realistic way so
    that one can be able to provide reliable results to be compared against
    existing experimental data. The dynamics in electron-molecule collisions
    is strongly affected by the inclusion (and a balanced treatment) of
    exchange, polarization and multichannel coupling effects. In this talk I
    will focus on analyzing the influence that the effects of channel
    coupling have upon the magnitude of elastic and electronically inelastic
    cross section results. According to our experience, an accurate
    description of the excited states of the target and the use of suitable
    strategies to construct the open-channel space (number and type of
    states that become energetically accessible to the molecular target
    during the collision process) represent crucial steps in the definition
    of the level of channel coupling to be used in the scattering
    calculations. These findings will be illustrated by recent applications
    involving the description of electron scattering by phenol, ethylene and
    thiophene molecules in which the multichannel coupling effect was
    treated in a growing level of complexity.
