Inelastic Scattering from Light Nuclei—the Alpha-Particle Model forBe9

Abstract: The inelastic scattering of nucleons, deuterons, and alpha particles from light nuclei is discussed in terms of direct interactions. The validity of this description, and of the approximations made here and by other authors in calculating cross sections, are analyzed in detail. Physical arguments are given for the use of a collective representation of light nuclei, in order to explain the preferential excitation of certain well-defined nuclear states by short-wavelength projectiles. As an example, the alpha-pa… Show more

“…The orbital angular momentum projections K L for the rotational intrinsic state suggested by these observations on the LS structure of 9 Be are also consistent with the appealing intuitive description of these bands as arising from nuclear molecular rotation. In a molecular description, 9 Be is composed of two α clusters plus a single valence neutron, which occupies a molecular orbital in the potential generated by the clusters [69][70][71][72]. Within each α particle, the spins of both protons and of both neutrons must couple to give zero resultant spin, leaving only the spin contribution of the last neutron (S = 1/2).…”

“…7 The ground state has a spin of 3/2, with K=3/2 and the first excited state in the ground state rotational band is taken to be the 2.43-MeV state which has a spin of 5/2. If we assume the equilibrium distance between the two alphas is given by 2£, we obtain the following expressions for the elastic scattering cross section and the inelastic 0.34…”
