Recent experiments with the Zero Gradient Synchrotron at Argonne have revealed startling differences in the way protons of different spins scatter elastically. A group from the University of Michigan and Argonne National Lab led by Alan Krisch has found that for protons polarized normal to the scattering plane, elastic scattering at large momentum transfers is about four times more probable for spins parallel than anti‐parallel.
