The formation of singly charged carbon clusters, C-n(+), with groups of clusters at n = 1-35, n similar to 160-400 and clusters with n similar to 8000 was observed. On applying either high laser energy or ultrasound, the position and intensity of the maxima change and a new group of clusters at n similar to 70-80 is formed. High carbon clusters consist of an even number of carbons while the percentage of odd-numbered clusters is quite low (<= 5-10%). On increasing the laser energy, the maximum of ionization (at n similar to 200 carbons) is shifted towards the lower m/z values. It is suggested that this is mainly due to the disaggregation of the original NDs. However, the partial destruction of NDs is also possible. The carbon clusters (n similar to 2-35) are partially hydrogenated and the average value of the hydrogenation was 10-30%."@en . "Panyala, Nagender Reddy" . . "RIV/00216224:14310/09:00028539" . .
