This discusses a representation of neutron balance in which the adjoint flux has no physically simple meaning. In this case, the function adjoint to the neutron absorption density may be defined as the fuel-importance function, and it plays the principal role in perturbation theory. Its application to the minimum-critical-mass problem gives a more physically clear interpretation.
