Properties of a neutron
WebThe neutron is a particle with a spin of one-half. It is the interaction of this spin with the spin state of the nucleus of an atom that determines the scattering property of a neutron with that atom. This spin-spin interaction leads both to coherent scattering, and hence diffraction effects, and to incoherent scattering, which for the purposes ... WebA neutron is an electrically neutral elementary subatomic particle with mass almost 2000 times that of the electron. The neutron lifetime as a free particle is about 15 min in spite …

The mass of a neutron cannot be directly determined by mass spectrometry since it has no electric charge. But since the masses of a proton and of a deuteron can be measured with a mass spectrometer, the mass of a neutron can be deduced by subtracting proton mass from deuteron mass, with the difference being the mass of the neutron plus the binding energy of deuterium (expressed as a positive emitted energy). The latter can be directly measured by measuring the …
