Abstract

Angle-resolved ion yield spectroscopy revealed that ionic fragmentation of aTdsymmetry moleculeSiF4is anisotropic after F1sphotoexcitation. The anisotropic fragmentation is interpreted as being due to preferential bond rupture at the F1score-hole site. The probability of the bond rupture at the core-hole site is three times as large as those at other sites. The origin of the preferential bond rupture is discussed in terms of symmetry breaking due to dynamical core-hole localization.
