Abstract： Titanium-carbon anion clusters with a mass range up to 1800 amu have been generated in a Smalley-type cluster source involving a target rod composed of titanium and graphite powders, and have been analysed by time-of-flight mass spectrometry. In the lower mass range (up to 1200 amu), our mass spectrum reproduces all the magic numbers, which have been reported previously, i.e., Ti3C-8, Ti6C-13, Ti7C-13, Ti9C-15, Ti13C-22, and Ti14C-24, in spite of many differences in experimental conditions. In the higher mass range (1200-1800 amu), we observe new magic numbers at Ti15C-26, Ti20C-33/Ti20C-34 and Ti25C-42, which cannot be accounted for by the previously proposed structural growth patterns. All the magic and local maximum TixC-y peaks have a metal-to-carbon ratio of approximately 1:1.7. The present results suggest a further complexity to the structural growth patterns of the transition metal-carbon mixed cluster systems.
