Popis: A search for particle-bound polyneutron systems (/sup 6/n-/sup 12/n) produced in approx. 700-MeV proton interactions with uranium has yielded negative results. A radiochemical technique was used. The limits on production cross section: 10/sup -3/ to 10/sup -5/..mu..b: are many orders of magnitude lower than previous limits at comparable energies, are lower than predictions based on extrapolation of yields of other neutron-rich species, and are in contrast to the positive results reported recently from work with 24-GeV protons on tungsten.
