WebbA theory of radiation has been given by the author which rests on a more definite basis. It appears that one can treat a field of radiation as a dynamical system, whose interaction with an ordinary atomic system may be described by a Hamiltonian function. Webb7 maj 2024 · 1 Answer Sorted by: 3 As you did'nt define your terms, I will use the definition of exponential dispersion model used in Definition of exponential family with dispersion parameter, which is f ( y θ, ϕ) = exp ( y θ − b ( θ) a ( ϕ) + c ( y, ϕ)) which is an exponential family in θ, for each fixed ϕ.
