Fundamental article: Proton rot
The spontaneous rot of free protons has never been watched, and the proton is subsequently viewed as a stable molecule. Notwithstanding, some terrific brought together hypotheses of molecule material science foresee that proton rot ought to happen with lifetimes of the request of 1036 years, and test pursuits have created lower limits on the mean lifetime of the proton for different expected rot items.
Tests at the Super-Kamiokande identifier in Japan gave lower limits for proton mean lifetime of 6.6×1033 years for rot to an antimuon and an impartial pion, and 8.2×1033 years for rot to a positron and a nonpartisan pion.[6] Another trial at the Sudbury Neutrino Observatory in Canada hunt down gamma beams coming about because of lingering cores coming about because of the rot of a proton from oxygen-16. This examination was intended to catch rot to any item, and made a lower utmost to the proton lifetime of 2.1×1029 years.[7]
Then again, protons are known to convert into neutrons through the methodology of electron catch (additionally called opposite beta rot). For nothing protons, this procedure does not happen spontaneously however just when vitality is supplied. The mathematical statement is:
p+ + e− → n + ν
e
The methodology is reversible; neutrons can change over once again to protons through beta rot, a typical type of radioactive rot. Actually, a free neutron rots along these lines, with a mean lifetime of around 15
