text: Metal nanoparticles host localized plasmon excitations that allow the manipulation
of optical fields at the nanoscale. Despite the availability of several techniques
for imaging plasmons, direct access into the symmetries of these excitations remains
elusive, thus hindering progress in the development of applications. Here, we
present a combination of angle-, polarization-, and space-resolved cathodoluminescence
spectroscopy methods to selectively access the symmetry and degeneracy of plasmonic
states in lithographically fabricated gold nanoprisms. We experimentally reveal
and spatially map degenerate states of multipole plasmon modes with nanometer
spatial resolution and further provide recipes for resolving optically dark and
out-of-plane modes. Full-wave simulations in conjunction with a simple tight-binding
model explain the complex plasmon structure in these particles and reveal intriguing
mode-symmetry phenomena. Our approach introduces systematics for a comprehensive
symmetry characterization of plasmonic states in high-symmetry nanostructures.
