Abstract: The dominant decay mode of atomic nuclei is beta decay (β-decay), a process that changes a neutron into a proton (and vice versa). This decay offers a window to physics beyond the standard model, and… read more here.

Abstract: Recently the lifetime of the excited 3d94s22D3/2 in Ni- was measured to be 15.1±0.4 s [Phys. Rev. A 93, 012512 (2016)2469-992610.1103/PhysRevA.93.012512]. This deviates from results from nonrelativistic, within the LS-approximation, calculations for this forbidden magnetic-dipole… read more here.
