Abstract
The absolute values for the cross sections of the ionization continuum of H2 had been measured at low energy (15.3-17.2eV) Both absorption and ionizationspectra were simultaneously recorded with linear response and absolute values, using a 10m normal incidence monochromator installed on a synchrotron undulator beamline. The vibrational thresholds can be clearly seen as steps in the experimental data. The agreement between experimental values and theoretical ones is very good except around the first and second vibrational thresholds where the experimental data exceed the theoretical ones.
