Gamma detected NMRON spin echo profiles for equal turn angle pulses-zero skin effect

The theoretical profiles for both principal (τ₂=τ₁) and harmonic (τ₂=1/2τ₁, 2τ₁) spin echoes in gamma detected triple pulse NMRON experiments are systematically calculated for a wide range of the parameter for inhomogeneous broadening using analytic expressions derived from physical ensemble rotation considerations, specific to a pure Zeeman Hamiltonian. In the absence of skin effects, and assuming equal turn angle pulses, these calculations provide the optimum turn angle conditions for maximum spin echo amplitude.
