Evidence of bottom-quark--state production has been searched for in p-Fe interactions at 400 GeV/c by looking for multimuon final states. Muons in such final states could come from B ..-->.. psi ..-->.. 2..mu.. decay accompanied by a muonic decay of B-bar (or B-bar ..-->.. D-bar ..-->.. ..mu.. chain) or from a combination of B and D muonic decays. With the assumption of a 10% branching ratio for B ..-->.. ..mu..X, a search for several specific decay modes yields an upper limit for the B production cross section of < or approx. =5 nb/nucleon.
