报告摘要：

　　Radiation damages to living tissue play an important role in DNA mutation. In addition to the primary ionizing and secondary particles damaging mechanism, molecular environment can also play important role. Here, we report two new ionization-fragmentation mechanisms which can only be happened in hydration/cluster system: (i) the intermolecular Coulombic decay (ICD) where one primary ionization can eject electron from both of two units in molecular cluster; (ii) catalytic effect of water environment on biomolecular dissociation. The above-mentioned mechanisms of bio-/organic-relevant molecules like tetrahydrofuran, acetone, etc, will be introduced as examples.
