Abstract:
Pulsed field gradient echo NMR methods for non-invasive and non-destructive studies of diffusion of fluids or gases was described. Three anal. expressions for the spin-echo intensity as a function of the gradient in a pulsed field gradient NMR expt. for spins diffusing in a sphere with reflecting walls are restudied. None of the published formulas are completely correct. By numerical comparisons the correct formula is found.
