Concepts for direct frequency-comb spectroscopy of ${}^{229\text{m}}$Th and an internal-conversion-based solid-state nuclear clock

Lars von der Wense, Chuankun Zhang

A new concept for narrow-band direct nuclear laser spectroscopy of ${}^{229\text{m}}$Th is proposed, using a single comb mode of a vacuum ultraviolet frequency comb generated from th…
