Nuclear spin relaxation of liquid {sup 3}He in porous glass has been studied. In addition to measurements of the longitudinal spin relaxation time T{sub 1} by a usual pulsed SQUID NMR, measurements of the transverse spin relaxation time T{sub 2} have been performed by using a newly developed SQUID NMR method to observe a spin echo signal. Temperature and frequency dependences of T{sub 1} and T{sub 2} have been measured. A simple model is proposed which explains the main features of the experimental results.
