With the transition radii for protons and neutrons chosen to be 3.9 fm and 4.1 fm respectively, good fits to the experimental cross sections are obtained. In contrast to the distorted wave Born approximation ( dwba ) calculations using optical model codes, we find the present work is able to...
? Assuming the atom is uncharged, how many electrons are present? Protons and Neutrons:Protons and neutrons constitute two sorts of subatomic particles. Protons are drawn towards a negative charge, as they constitute a positive charge. N...
. Nuclear equations are used to represent nuclear reactions, which shows the atomic and mass numbers of the nuclei and particles. Balancing a nuclear equation is essential due to the conservation of charge, and is done by ensuring that the sum of the protons and neutrons of ...
Discovery of the Earth's Van Allen radiation belts by instruments flown on Explorer 1 in 1958 was the first major discovery of the Space Age. The observation of distinct inner and outer zones of trapped megaelectron volt (MeV) particles, primarily protons at low altitude and electrons at high...

A ^{235} U atom (Z = 92, Atomic mass = 235.043924 amu) consists of protons (Mass = 1.00728 amu), neutrons (Mass = 1.00867 amu) and electrons (Mass = 0.000549 amu). Calculate the binding energy per nucFind the ...
nuclei with Ales5/ A2540 Nucleon-induced reactions and scatteringThe polarization transfer coefficient, α t, has been measured for (p, n) reactions on 2H, 6Li and 7Li using transversely polarized protons incident at energies of 30 and 50 MeV. The transverse polarization of neutrons emitted ...

electrons and neutrons that material particle properties come from matter waves, if the molecular force constants are very large (Extension of the Maxwell relation for the translational energy). In contrast to the electromagnetic waves or protons, the velocity of propagation is different from the ...
