Experimental verification of position-dependent angular-momentum selection rules for absorption of twisted light by a bound electron

We analyze the multipole excitation of atoms with twisted light, i.e, by a vortex light field that carries orbital angular momentum. A single trapped 40Ca+ ion serves as a localized and positioned probe of the exciting field. We drive the transition and observe the relative strengths of different tr...
