The effects of Mg Ka X-rays on furan overlayers on the Ru(001) surface have been investigated using X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS). It was found that X-ray beams can polymerize furan multilayers condensed at 80 K, resulting in the appearance of new emission features at 532.8 eV in the O Is XPS spectra and at similar to 3 eV in the UPS spectra. In contrast, monolayer furan on Ru(001) at 80 K shows no signs of polymerization under the same conditions.
