Microscopic Structure of ΔJπ = 1+ Excitations in sd-Shell Nuclei

  • B. H. Wildenthal

The subject of this paper is the theoretical structure of even-parity dipole excitations in light nuclei. The defining characteristics of “light” nuclei in the present context are that they have approximately equal numbers of neutrons and protons and that the “active” nucleon orbits needed to describe their structure in the conventional shell-model representation are those of a single, multiply-degenerate, level of the three-dimensional harmonic oscillator. Physical phenomena by which this class of excitations can be experimentally observed include magnetic dipole (Ml) electromagnetic excitations, Gamow-Teller beta decay, radiative meson capture, and hadronically-induced charge-exchange processes such as the (p,n) reaction.
