Dynamics of electromagnetically induced water molecule fragmentation
Anton V. Bibikov, Sergei N. Yudin, Maria M. Popova +2
The development of intense high-energy radiation sources and the improvement of techniques for detecting charged fragments have made possible experiments on multiple ionization of…
General properties of the RABBITT at parity mixing conditions
Maria M. Popova, Sergei N. Yudin, Alexei N. Grum-Grzhimailo +1
Parity mixing in photoionization, i.e. when emitted electrons have different parities but the same energy, causes interference observable only in angle-resolved measurements. The i…

Maria M. Popova, Sergei N. Yudin, Alexei N. Grum-Grzhimailo +1
The RABBITT setup is theoretically studied for various combinations of XUV and IR field components polarization: 'linear+linear', `linear+circular' with crossed propagation directi…
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…
