... same number of protons and neutrons. This is when they are the most stable. Large atoms with around 83 protons or more are so large that they too are unstable. If atoms are too unstable, they will decompose, or radioactively decay, releasing different types of particles in order to become more stabl ...

... neutron capture. Captures on a seed nucleus (mostly 56Fe) lead to the production of a βunstable nucleus (e.g. 59Fe). • Outcome depends on relative time-scales for neutron addition and decay. • s-process: slow addition, so that unstable nuclei have time to undergo decay • Nuclei form along the stabil ...

... ½… The mass of the neutrons should be of the same order as the electron mass and in any event not larger than 0.01 proton masses. The continuous beta spectrum would then be explained by the assumption that in beta decay a neutron is emitted in addition to the electron such that the sum of the energi ...

P-nuclei
p-Nuclei (p stands for proton-rich) are certain proton-rich, naturally occurring isotopes of some elements between selenium and mercury which cannot be produced in either s- or r-process.
