Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 x 10^-27 kg, which is 1,836 times the mass of an electron. Protons, together with electrically neutral particles calle
Evaluated delayed neutron emission probabilities for 74 precursors and estimated probabilities for another 174 precursors have been combined with ENDF/B-V fission yields to map out delayed neutron yields as a function of mass number, proton number, and neutron number. For all fissioning systems, mor...
Neutron, neutral subatomic particle that, in conjunction with protons, makes up the nucleus of every atom except ordinary hydrogen (whose nucleus has one proton and no neutrons). Along with protons and electrons, it is one of the three basic particles ma

A model for the mass-number independence of the antiproton annihilation on nuclei at low energiesdoi:10.1016/S0370-2693(01)01284-9A simple model explaining the recently observed approximate independence of the annihilation cross section on light nuclei at low energies is proposed. The salient ...
Moreover, one mole equals 6.022e23 units, and we know that proton weighs 1.0079 g. Then dividing the weight of proton with mole number we get (1.0079/ 6.022e23) proton mass: 1.6737e-24 g. Note: in the atom, there is an electron to balance the proton charge. Also, we can do this ...

Good agreement with experimental data from the three-point filter Δ(3)(N) with N odd has been found for both the neutron and proton gaps. The results of our study support earlier findings [W. Satua, J. Dobaczewski, W. Nazarewicz, Phys. Rev. Lett. 81 (1998) 3599] that the mass...
