OSCILLATORY FREE-INDUCTION DECAY SIGNALS IN THE ANGULAR-DISTRIBUTION OF NUCLEAR RADIATION IN FERROMAGNETIC METALS UNDER STRONG INHOMOGENEOUS BROADENING

The problem of the oscillatory free induction decay in the angular dis tribution of nuclear radiations is theoretically examined for inhomoge neous linewidths, with and without the influence of the skin effect, u tilizing the method of concatenation of perturbation factors. The seco nd rank detection tensor applicable to gamma detected pulsed NMRON sig nals from ferromagnetic metals is examined for axial geometry. Importa nt extensions to the pulse area theorem originally developed only for the first rank detection tensor are proposed for second rank tensors.
