The multiplication factor that takes neutron leakage into account is the effective multiplication factor – k eff, which is defined as the ratio of the neutrons produced by fission in one neutron generation to the number of neutrons lost through absorption and leakage in the preceding neutron generation.The effective multiplication factor (k

The classical expression for kinetic energy, E = mv2/2, is sufficiently accurate because even a kinetic energy of 100 MeV is still only about one-tenth of the rest-mass energy of a neutron (939.55 MeV). For velocity v in meters per second and kinetic ene~,, E in MeV, E = 5.227 X 10-ls # (12-1) and v = 1.383 X 107E1~.

3.1K views. The gyromagnetic ratio, symbol γ, of a particle or system is the ratio of its magnetic moment to its spin angular momentum, or For nucleons, the ratio is conventionally written in terms of the proton mass and charge, by the formula The neutron's gyromagnetic ratio, symbol γn, is −1.832 471 71(43) × 108 rad⋅s−1⋅ T −1. The best modern (1986) values for neutron mass by this technique are provided by Greene, et al. These give a neutron mass of: m neutron = 1.008 644 904 (14) u.
