Title: Fragmentation of endohedral fullerene H o 3 N @ C 80 in an intense femtosecond near-infrared laser field

The fragmentation of gas phase endohedral fullerene, Ho 3N@C 80, was investigated using femtosecond near-infrared laser pulses with an ion velocity map imaging spectrometer. Here, we observed that Ho + abundance associated with carbon cage opening dominates at an intensity of 1.1 x 10 14 W/cm 2. As the intensity increases, the Ho + yield associated with multifragmentation of the carbon cage exceeds the prominence of Ho + associated with the gentler carbon cage opening. Moreover, the power law dependence of Ho + on laser intensity indicates that the transition of the most likely fragmentation mechanisms occurs around 2.0 x 10 14 W/cn 2.
