HEXADECAPOLE INTERACTING BOSON APPROXIMATION STRUCTURE FUNCTIONS IN NEODYMIUM ISOTOPES

Low-lying hexadecapole states in stable even-even neodymium isotopes have been investigated by means of inelastic electron scattering. Transition charge densities were extracted in a Fourier-Bessel analysis of the form factors. The analysis of the experimental results within the interacting sdg-boson model with only one g boson allowed the extraction of the radial shapes of the hexadecapole structure functions of three of the different boson-pair configurations (i.e., dd, sg, and dg) involved in the hexadecapole excitations.
