Abstract
The angular distribution of neutrons with energies above 20 Mev produced by bombardment with the 330-Mev proton beam in the 184-in. cyclotron of Be, Al, Cu, and U targets has been measured with carbon detectors. The full widths at half-maximum obtained are 54° for Be, 59° for Al and Cu, and 58° for U. Experimental details and the resulting curves are given.
