Description

We demonstrate the first laser excitation of an atomic nucleus and perform precision spectroscopy of the nuclear quadrupole structure emerging in a solid-state environment.
This allows us to determine nuclear shape parameters with unprecedented accuracy and determine the sensitivity of the nuclear clock transition to a variation of the fine structure constant.
