A Method of Transforming the Prompt Decay Constants αiinto the Static Reactivity ρs

“…An approximate solution of order N must be considered in carrying out practical numerical calculation: 'J(a,) . (9) Equation ( 9) may be considered to constitute a generalized characteristic equation relating the prompt decay constants to the effective multiplication constant of the system.…”
