Experimental β-decay studies contribute significantly to improving our understanding of exciting nuclear phenomena emerging far from stability, such as β-delayed multiple-particle emission [1–3], evolution of the shell structure [4], and the appearance of so-called “islands of inversion” [5]. The great success of β-decay experiments in probing ground- and excited-state properties is due...
High-precision measurements of the beta spectrum shape and beta-neutrino angular correlation parameter allow to test for exotic scalar and/or tensor currents in the weak interaction. These measurements are the goal of the WISArD collaboration at ISOLDE [1]. When aiming for the highest precision in the description of the shape of the beta energy spectrum, even small Standard Model effects,...
Alpha decay is known for more than a century, however a global microscopic description has only been developed recently by Mercier al. [1]. With the framework of covariant energy density functional, using a least action principle, the half-life of medium and heavy nuclei are in agreement within one order of magnitude with experimental values [2].
Moreover, a new type of decay was predicted...
The thorium-229 nucleus contains an isomeric state with a low excitation energy, making it accessible to laser excitation. It is presently the only known candidate for the development of a nuclear clock [1,2,3,4] which will enable testing fundamental principles in physics, such as e.g. potential variations of fundamental constants [5] or the search for ultralight dark matter candidates [6]....
