The F2 laser emission in Ne matrixes at 160.6 nm is reported for the first time. Its excitation spectrum in the 11-16 eV range has been recorded by means of tunable synchrotron radiation. Anomalous envelopes of vibrational progressions occurring in the gas phase due to avoided crossing of ion-pair 1Su+ states and Rydberg 1Su+ states are shown to disappear in Ne matrixes. The matrix spectra are discussed in terms of a deperturbed C1S+ ion-pair and strongly blue-shifted I1Su+ and H1.product.u Rydberg states. [on SciFinder (R)]
