How to determine rate of decay

WebExplain how a body's rate of decomposition is affected by the way the death occurred and the environment in which it is placed. Decomposition depends on the kind of environment the body is left in. If the body is placed in hot temperatures it will decay much faster than if it were to decay in colder temperatures. WebDecay rate. This section uses natural units, where = =. The lifetime of a particle is given by the inverse of its decay rate, , the probability per unit time that the particle will decay.For a particle of a mass M and four-momentum P decaying into particles with momenta , the differential decay rate is given by the general formula (expressing Fermi's golden rule)
