Conference paper


Covariance and correlation coefficient mapping techniques are utilized to investigate the formation mechanism of titanium carbon clusters in a laser vaporization source, and also to elucidate the details of fragmentation of these clusters under excitation with an intense femtosecond laser pulse (~ 1015 W/cm2 at 120 fs). This study, and a previous investigation of the Coulomb explosion of ammonia clusters, demonstrates the potential which covariance mapping has in discerning the details of cluster formation and fragmentation processes. Particular attention is paid to the titanium metallocarbohedrene (Met-Car), Ti8C12.
