Abstract
The possibility of extending the microscopicα-decay theory to exotic decay modes is investigated. It is argued that the strong Pauli distortions in the antisymmetrized wave function of the open channel favour this possibility. The microscopic description can be reduced to a one-body picture; the structure information is then contained in a spectroscopic factor. Existing microscopic calculations fromα- up to16O-decays justify a simple unified bulk formula for the spectroscopic factor. In this way a semiempirical formula for the decay constant is obtained depending on 1 parameter only (for odd and even nuclei, respectively). This formula describes all decay modes in a unified way and yields an excellent reproduction of the known exotic decay rates. It is thus well-suited for the unambiguous prediction of yet unmeasured decay constants.
