By using the analytical superasymmetric fission model it is shown that all ''stable'' nuclei lighter than lead with Z>40 are metastable relative to the spontaneous emission of nuclear clusters. An even-odd effect is included in the zero point vibration energy. Half-lives in the range 10/sup 40/--10/sup 50/ s are obtained for Z>62. The region of metastability against these new decay modes is extended beyond that for ..cap alpha.. decay and in some cases, in the competing region, the emission rates for nuclear clusters are larger than for ..cap alpha.. decay.
