The relaxation dynamics of resonantly excited helium droplets by XUV radiation has been investigated. Using an XUV-UV pump-probe setup, we initially resonantly excite the droplet and observe the various relaxation pathways prior to UV ionization. From the results we can clearly see an initial droplet band relaxation followed by the electron relaxing to an atomic state. Here, we will present the time resolved results for various resonant excitations and droplet sizes.
