Cluster decays of [sup 112[minus]120]Ba nuclei are calculated within a preformed cluster model. The [alpha]-nuclei [sup 4]He, [sup 8]Be, [sup 12]C, [sup 16]O, and [sup 20]Ne are predicted as the possible decay modes, lying within the limits of present experimental methods. Other than the [alpha] particle, [sup 12]C decay of [sup 112]Ba is shown to be the most probable one with half-life time [ital T][sub 1/2][similar to]10[sup 4] s, stressing the role of doubly magic [sup 1][sub 50][sup 00]Sn daughter nucleus in cluster radioactivity. The use of different [ital Q] values for [ital T][sub 1/2] estimates and presence of nuclear structure effects in Geiger-Nuttall plots are also discussed.
