    "abstract": "We study the carbon-dope aluminum clusters by using time-of-flight mass\nspectrum experiments and {\\em ab initio} calculations. Mass abundance\ndistributions are obtained for anionic aluminum and aluminum-carbon mixed\nclusters. Besides the well-known magic aluminum clusters such as Al$_{13}^-$\nand Al$_{23}^-$, Al$_7$C$^-$ cluster is found to be particularly stable among\nthose Al$_n$C$^-$ clusters. Density functional calculations are performed to\ndetermine the ground state structures of Al$_n$C$^-$ clusters. Our results show\nthat the Al$_7$C$^-$ is a magic cluster with extremely high stability, which\nmight serve as building block of the cluster-assembled materials.",
