Der Einfluß der Zweibereichdiffusion auf die Spinechodämpfung unter Berücksichtigung der Relaxation bei Messungen mit der Methode der gepulsten Feldgradienten



Echo attenuation due to both diffusion and relaxation in two phase systems is investigated theoretically for the pulsed field gradient experiment. It is found that the general formulae are rather complicated. In some special cases however a separation of relaxation and diffusion terms is possible. The practical importance of these cases is discussed.
