Resonant two-photon ionization of helium atoms studied by attosecond interferometry

Lana Neoričić, David Busto, Hugo Laurell +15

We study resonant two-photon ionization of helium atoms via the $1s3p$, $1s4p$ and $1s5p^1$P${}_1$ states using the 15${}^{\mathrm{th}}$ harmonic of a titanium-sapphire laser for the exc…
