We propose a theorem for the quantum operator that corresponds to the solution of the Helmholtz equation, i. e., @@@ integral integral integral V (x(1),x(2),x(3)) vertical bar x(1),x(2),x(3)) < x(1),x(2),x(3)> d(3)x = V (X-1,X-2,X-3) = e(-lambda 2)/4 : V (X-1,X-2,X-3) :, @@@ where V (x(1), x(2), x(3)) is the solution to the Helmholtz equation del V-2 + lambda V-2 = 0, the symbol : : denotes normal ordering, and X-1, X-2, X-3 are three-dimensional coordinate operators. This helps to derive the normally ordered expansion of Dirac's radius operator functions. We also discuss the normally ordered expansion of Bessel operator functions.
