Abstract
Recently a high-resolution proton recoil spectrometer was used to measure the neutron spectrum from 20-MeV proton bombardment of . Evidence for levels in at 1.4- and 3.2-MeV excitation was presented. Using time-of-flight techniques, we have remeasured the neutron spectrum and find no evidence for these levels.
