Laser ultraviolet fragmentation of homogeneous (CF$_3$I)$_n$ clusters in a molecular beam and (CF$_3$I)$_n$ clusters inside of large (Xe)$_m$ clusters or on their surface

The fragmentation of homogeneous (CF$_3$I)$_n$ clusters (where $n\leq45$ is the average number of molecules in a cluster) in a molecular beam, as well as (CF$_3$I)$_n$ clusters inside of large (Xe)$_m$ clusters (where $m\geq100$ is the average number of atoms in a cluster) or on their surface, by laser ultraviolet radiation has been studied. It has been found that the indicated three types of (CF$_3$I)$_n$ clusters have different stabilities with respect to fragmentation and strongly different dependences of the fragmentation probability on the energy of ultraviolet radiation. Fragmentation at low energies and the weakest energy dependence of the probability of fragmentation are observed for homogeneous clusters, a stronger dependence is characteristic of (CF$_3$I)$_n$ clusters localized inside (Xe) m clusters, and the strongest dependence is observed for (CF$_3$I)$_n$ clusters on the surface of (Xe)$_m$ clusters. Possible reasons for such a character of the observed dependences have been discussed.
