Circular Dichroism in Multiphoton Ionization of Resonantly Excited Helium Ions near Channel Closing

Rene Wagner, Markus Ilchen, Nicolas Douguet +16

The circular dichroism (CD) of photoelectrons generated by near-infrared (NIR) laser pulses using multiphoton ionization of excited He${}^{+}$ ions in the 3p(m=+1) state. The ions were…
