A unique decay process: beta delayed emission of a proton and a neutron by the Li halo nucleus

D. Baye, P. Descouvemont, E. M. Tursunov

The neutron-rich Li halo nucleus is unique among nuclei with known separation energies by its ability to emit a proton and a neutron in a decay process. The branching ra…

Beta delayed emission of a proton by a one-neutron halo nucleus

D. Baye, E. M. Tursunov

Some one-neutron halo nuclei can emit a proton in a beta decay of the halo neutron. The branching ratio towards this rare decay mode is calculated within a two-body potential model…

Self-interaction errors in nuclear energy density functionals

N. Chamel

When applied to a single nucleon, nuclear energy density functionals may yield a non-vanishing internal energy thus implying that the nucleon is interacting with itself. It is show…
