Resumen:
We present a theoretical study of H2 ionization by photons of a few hundreds
of eV. Accurate bound and continuum states are obtained by using B-spline
basis functions. In agreement with a simple model by Cohen and Fano [6], we
observe interference effects that can be interpreted as a result of the coherent
emission from both molecular centres. Nevertheless, significant discrepancies
are found at low electron energies, in agreement with recent experimental
observations. The origin of this anomalous behaviour at low electron energies
is discussed in detail.
