This paper presents results of a beam-dump experiment performed at the Brookhaven alternating-gradient synchrotron to search for prompt sources of neutrinos and axionlike particles. We observe no excess of νₑ or ν_μ events, and no excess in neutral-current events over that expected from neutrinos from π and K decays. We report on limits of prompt particle-production cross sections and lifetimes.
