In this work, the single ionization of aligned H2 molecules by 54 eV impinging electrons is analysed. Fully differential cross sections are calculated by means of a multicenter CDW-EIS model which explicitly considers the multicenter nature of the molecular ion. Present results are contrasted with the recent experimental data and reported calculations obtained with the time-dependent close-coupling method (TDCC). These exhibit a good overall description of the angles at which the FDCS peaks and the width of these structures.
