40Ca(n,n)self-consistent density-dependent Hartree-Fock fieldoptical model potentialWe use the self-consistent density-dependent Hartree-Fock field as the real part of the optical model potential. Introducing a phenomenological imaginary potential, we describe elastic scattering of protons and neutrons ...

{eq}Z {/eq} is the number of protons, {eq}N {/eq} is the number of neutrons {eq}m_p = 1.007825 u {/eq} is the mass of proton, {eq}m_n = 1.008665 u {/eq} is the mass of neutron, {eq}M {/eq} is the mass of nucleus in amu, and ...
A different type of symmetry violation just might be, however. After all, quarks — the building blocks of protons and neutrons—aren’t the only subatomic particles out there. They have relatives known as leptons, a category that i...
In this process, two neutrons inside the decaying nucleus are converted into two protons and two electrons without emitting any neutrinos that violate the lepton number conservation. The neutrino appears as a virtual intermediate Majorana particle [1,2,3,4,5]. Although predicted long back in 1939...
