The yield and size distribution of single-wall carbon nanotubes were investigated on samples prepared by arc discharge between graphite electrodes in a He atmosphere with the positive electrode filled with mixtures of 2 metallic elements, Fe and Ni. The yield exhibits its maximum if the ratio of Fe to Ni is 1, and, concurrently, the distribution of the tube diameter is narrowest. The average diameter is found to be independent of the ratio and is about 1 nm.
