It is shown that using dispersion-theoretical formulas for the electromagnetic self-energies of the nucleons, which involve their electromagnetic form factors, the mass difference between the neutron and the proton can be satisfactorily explained. The expressions for the form factors involved have to ...

Aproton(mass1.6726×10−27kg)andaneutron(mass1.6749×10−27kg)at rest interact to form a deuterium nucleus (heavy hydrogen).In this process,a gamma ray (high energy photon) is emitted.The energy of this gamma ray is measured to be 2.2MeV≡2.2×106 eV. a) What is the mass of the...
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...
We discuss the Cottingham formula and evaluate the proton–neutron electromagnetic mass difference exploiting the state-of-the-art phenomenological input. We decompose individual contributions to the mass splitting into Born, inelastic and subtraction terms. We evaluate the subtraction-function contribution ...
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
Neutrino mass, proton decay and dark matter in TeV scale universal extra dimension models We show how the problem of small neutrino masses and suppressed proton decay can be simultaneously resolved in 6D universal extra dimension models (UED's) ... RN Mohapatra,A Pérez-Lorenzana - 《Physical ...
Proton-neutron mass difference in Sudarshan's Theory of Universal Primary Interactions We have computed the neutron-proton mass difference in Sudarshan's Universal Theory of Primary Interactions by appealing to the Feynman-Speisman prescripti...

Operators for the point-proton and point-neutron radii, form factors and the electric dipole operator were consistently transformed. The dipole polarizablility αD was computed using the equations-of-motion (EOM) method truncated at the two-particle-two-hole level (that is, the EOM-IMSRG(2,2...
