... shown that any symmetric, traccless, divergenceless second-rank tensor field that satisfies the Helmholtz ('<iuation can be expressed in terms of two scalar potclltials that satisfy the Helmholtz ('qualion. Two such exprcssions are given, which are adapted to the spherical or cylindrical coordinates. The application to the linearized Einstein theory is discussed. RESUMEN.
