Consequently, extremely intense, pulsating neutrino/antineutrino and leptonic pair fluxes will be emitted. During this stage several mass ejecta can be ejected from the stellar surface by the neutrinos and antineutrinos. These ejecta can be further accelerated to relativistic speeds by the electron/...
A free neutron—one that is not incorporated into a nucleus—is subject toradioactive decayof a type calledbeta decay. It breaks down into a proton, an electron, and an antineutrino (theantimattercounterpart of theneutrino, a particle with no charge and little or no mass); thehalf-lifefor...
Related to Neutron mass:Protons neu·tron (no͞o′trŏn′, nyo͞o′-) n.Abbr.n The electrically neutral nucleon, a baryon composed of two down quarks and one up quark, which has a mass 1,839 times that of an electron, is stable when bound in an atomic nucleus, but has a mean...
The neutron-proton mass difference is re-evaluated on the basis of new experimental data and knowledge from high-energy electron scattering that the electromagnetic form factors of the proton can no longer be considered as identical. Calculations are performed using second order perturbation in e. ...
19. Meson condensate influences weakly the equation of state of neutron star matter and it can soften the equation of state slightly. 介子凝聚的出现还使中子星物质的状态方程变软。 20. neutron 20. Assuming that it roughly takes t = E/W for the electron to loose all its energy and R = 5....
The tests selected for discussion are the finiteness of the neutrino mass in the electron volt region, the decay of protons into antileptons in the range of 1031± 1yr, and the detectability of neutron oscillations at all. The PUT group can also be tested by establishing the existence of ...
