The number of neutrons is the neutron number and determines the isotope of an element. For example, the carbon-12 isotope has 6 protons and 6 neutrons, while the carbon-14 isotope has 6 protons and 8 neutrons. The number of protons in a nucleus is the atomic number and defines the type of element the atom forms. Neutrons are usually found in atomic nuclei. The nuclei of most atoms consist of protons and neutrons, which are therefore collectively referred to as nucleons. The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton.

|Accuracy and Dose in Neutron Stimulated Emission Computed Tomography. Simulations in GEANT4 Книга по Требованию Anuj J. K. |
The technique’s sensitivity to high concentrations of iron combined with its non-invasive tomographic acquisition ability gives it a unique advantage over other imaging methods.
|Analytical Methods Using Instrumental Neutron Activation Analysis. Determining the Radionuclides, Concentrations and Differential Factors of Biological Samples Книга по Требованию Saheed O. Y. |
This book covers the basics of radioanalytical techniques which include sample preparation, irradiation and spectra analysis, and the dimensions and structures of the reactor used for this research.
|Fast-neutron reactor Книга по Требованию Frederic P. M. |
Such a reactor needs no neutron moderator, but must use fuel that is relatively rich in fissile material when compared to that required for a thermal reactor.
|Neutron Radiation Книга по Требованию Lambert M. S. |
|Small-Angle Neutron Scattering Книга по Требованию Lambert M. S. |
These are particularly useful because of the dramatic increase in forward scattering that occurs at phase transitions, known as critical opalescence, and because many materials, substances and biological systems possess interesting and complex features in their structure, which match the useful length scale ranges that these techniques probe.
|Mathematical modeling of neutron transport. Theoretical and computational point of view Книга по Требованию Milan H. |
The book may be very useful to researchers facing the task to upgrade a legacy diffusion code, but may also well serve as a concise overview of modern transport-theoretical techniques.
|This work proposes a new view on mechanism of formation of X-ray variability in accreting black holes and neutron stars Formation of the power spectrum in the accreting compact X-ray objects. Книга по Требованию Andrey M. |
The basic underlying physical assumption is that the observed variability of X-ray luminosity originates as the result of local fluctuations of the mass accretion rate, at all radii in the disk, that diffusively propagate outward.
