Coherent diffraction experiments on single particles using intense X-ray or XUV light sources have revolutionized the structural determination of fragile, short-lived nanoscale samples and their dynamics. However, electronic properties are also inherently encoded in the diffraction patterns, but their extraction requires new analysis methods. In our study, we employed a high-harmonic-generation (HHG) light source to perform NIR-XUV pump-probe experiments at photon energies near strong electronic resonances of helium droplets.

In this presentation, several of our analysis approaches to address challenges related to detection artifacts and the multicolor nature of HHG radiation will be discussed. Moreover, initial findings on ultrafast changes in the optical properties and, thus, on electron dynamics of helium nanodroplets will be presented.
