Fragmentation of endohedral fullerene H o3N @C80 in an intense femtosecond near-infrared laser field
Abstract
The fragmentation of gas phase endohedral fullerene, H o3N @C80 , was investigated using femtosecond near-infrared laser pulses with an ion velocity map imaging spectrometer. We observed that H o+ abundance associated with carbon cage opening dominates at an intensity of 1.1 ×1014W /c m2 . As the intensity increases, the H o+ yield associated with multifragmentation of the carbon cage exceeds the prominence of H o+ associated with the gentler carbon cage opening. Moreover, the power law dependence of H o+ on laser intensity indicates that the transition of the most likely fragmentation mechanisms occurs around 2.0 ×1014W /c m2 .
