ProtonenDripLinie
ProtonenDripLinie, or the proton drip line, is the boundary on the proton-rich side of the chart of nuclides beyond which nuclei cannot bind an additional proton. It is defined by the condition that the one-proton separation energy S_p becomes zero or negative, making proton emission energetically favorable. The line delineates the set of nuclides that are bound with respect to proton emission from those that are not. It is the proton-rich counterpart of the neutron drip line and is strongly influenced by the Coulomb repulsion between protons and by nuclear shell structure.
Locating the proton drip line relies on a combination of experimental measurements and theoretical models. Experimentally,
On the theory side, global mass models and energy-density functionals predict the position of the line. Influencing
Relevance: The proton drip line is important for understanding nucleosynthesis in proton-rich environments, such as the
