Description
Using covariant energy density functional approach, it was recently possible to describe alpha decay, on both medium mass and heavy nuclei [1]. Using the same formalism, a new mode of radioactivity was predicted [2]. In such a mode, 2 alpha particles are emitted back-to-back, contrary to a 8Be-like cluster mode. Cluster decay will also be analyzed with this approach [3].
Information brought by such a formalism on the preformation and the localization of the alpha particle in the nuclei will be discussed [4]. Indications on possible favorable candidates to experimentally search for 2 alpha decays with radioactive beams will also be given.
