Abstract

Photons carrying a well-defined orbital angular momentum have been proven to modify spectroscopic selection rules in atomic matter. Excitation profiles of electric quadrupole transitions have been measured with single trapped ⁴⁰ Ca ions for varying polarizations. We further develop the photo-absorption formalism to study the case of arbitrary alignment of the beam’s optical axis with respect to the ion’s quantization axis and mixed multipolarity. Thus, predictions for M 1-dominated ⁴⁰ Ar ¹³ , E3-driven ¹⁷¹ Yb and ¹⁷² Yb, and B-like ²⁰ Ne ⁵ are presented. The latter case displays novel effects, coming from the presence of a strong photon–magnetic dipole coupling.
