Evidence for Intermediate Structure in the Inelastic Scattering of Polarized Protons fromMg26andAl27

Abstract
Structure of variable widths from about 0.3 to 1.5 MeV has been observed in analyzing-power excitation functions for inelastic proton scattering from Mg26 and Al27. Statistical tests and significant cross correlations show that it is very unlikely that this structure is the chance effect of random fluctuations. Thus these data are evidence for intermediate structure.
