The first generalisation we might make is that if the neutron to proton ratio is about 1, then the isotope is likely to be stable. If we pull out all the isotopes with n/p not close to 1, say those with n/p ≥ 1.29 and those with n/p ≤ 0.775, we can construct a new table as shown below 1 :

nuclei with too few protons are to the left of the stability line and become more stable by emitting a beta- (b –)particle when a neutron converts into a proton; How nuclei change when they decay. Alpha decay. In alpha decay the unstable parent nuclei emits an alpha particle (2 protons and 2 neutrons) so the daughter nuclei has 2 less protons ...

Dec 21, 2007 · The neutron/proton ratio plays a major role. Neutrons function like a nuclear "glue" which holds nucleons together by overcoming the enormous repulsive interactions between protons. The more... The Hamiltonian for the deuteron, a bound-state of a proton and neutron, may be written in the form H = P2 p 2Mp + P2...
Sep 26, 2012 · The deuteron:proton ratio when the reactions stop is quite small, and essentially inversely proportional to the total density in protons and neutrons. Almost all the neutrons in the Universe end up in normal helium nuclei. For a neutron:proton ratio of 1:7 at the time of deuteron formation, 25% of the mass ends up in helium. Thus, xenon-118 has 54 protons and 118 - 54 = 64 neutrons, giving it a neutron-to-proton ratio of By examining Figure 21.2, we see that stable nuclei in this region of the belt of stability have higher neutron-to-proton ratios than xenon-118. The nucleus can increase this ratio by either positron emission or electron capture:

Neutron to proton ratio of an atom nucleus is the ratio of the number of neutrons to its number of protons. This ratio generally increases with increase in atomic number in a stable nuclei. Beta decay decreases the ratio of neutron to proton Eg: 614The neutron–proton ratio (N/Z ratio or nuclear ratio) of an atomic nucleus is the ratio of its number of neutrons to its number of protons.Among stable nuclei and naturally-occurring nuclei, this ratio generally increases with increasing atomic number.
The symmetry energy at sub- and supra-saturation densities has great importance for understanding the exact nature of asymmetric nuclear matter as well as neutron stars, but it is poorly known, especially at supra-saturation densities. We will demonstrate here whether or not the neutron-to-proton ratios from different kinds of fragments can determine the supra-saturation behavior of the ...
