Structure and electron dynamics of planetary states of Sr below the Sr${}^{+}$ $7d$ and $8p$ thresholds

Matthieu Génévriez, Christian Rosen, Ulrich Eichmann

In a combined experimental and theoretical study we investigate the $7dnl$ and $8pnl$ ($n\ge 11$, $l=9-12$) doubly-excited planetary states of Sr. The experimental spectrum was obt…
