The photoneutron cross section in 63Cu AND 141Pr

Abstract The (γ, n) cross section in 63 Cu and 141 Pr was measured from threshold to 33 MeV using bremsstrahlung from a betatron and observing the induced 62 Cu and 140 Pr activities. Under adequately high resolution both cross sections show structure, which is well described by the collective theory of Huber and Greiner.
