Using data corresponding to an integrated luminosity of 79 pb{sup -1} , D0 has searched for events containing multiple jets and large missing transverse energy in pp collisions at {radical}(s)=1.8 TeV at the Fermilab Tevatron collider. Observing no significant excess beyond what is expected from the standard model, we set limits on the masses of squarks and gluinos and on the model parameters m{sub 0} and m{sub 1/2} , in the framework of the minimal low-energy supergravity models of supersymmetry. For tan {beta}=2 and A{sub 0}=0 , with {mu}<0 , we exclude all models with m{sub q(tilde} {sub sign)}<250 GeV/c{sup 2} . For models with equal squark and gluino masses, we exclude m<260 GeV/c{sup 2} . (c) 1999 The American Physical Society.
