We present a completely microscopic approach for obtaining the preformation factors and the decay widths of [alpha], [sup 12]Ca, and [sup 16]O cluster decays. We start from realistic sing0[sub [minus]0.09][sup +0.13] [mu]b. The new isotope [sup 114]Ba represents the heaviest [ital N]=[ital Z]+2 nucleus known to date. With [Delta][ital E]-[ital E] telescopes we measured the total ([beta]-decay) half-life to be [ital T][sub [beta]]=0.43[sub [minus]0.15][sup +0.30] s and the partial [alpha]-decay half-life to be [ital T][sub [alpha]][ge]1.2[times]10[sup 2] s (1 MeV[le][ital E][sub [alpha]][le]4 MeV) for [sup 114]Ba. With track detectors we found a half-life for spontaneous [sup 12]C emission [ital T][sub [ital C]][ge]1.1[times]10[sup 3] s based on three carbon events.
