    Communication: X-ray coherent diffractive imaging by immersion in nanodroplets
    (Melville, NY : AIP Publishing LLC, 2015) Tanyag, Rico Mayro P.; Bernando, Charles; Jones, Curtis F.; Bacellar, Camila; Ferguson, Ken R.; Anielski, Denis; Boll, Rebecca; Carron, Sebastian; Cryan, James P.; Englert, Lars; Epp, Sascha W.; Erk, Benjamin; Foucar, Lutz; Gomez, Luis F.; Hartmann, Robert; Neumark, Daniel M.; Rolles, Daniel; Rudek, Benedikt; Rudenko, Artem; Siefermann, Katrin R.; Ullrich, Joachim; Weise, Fabian; Bostedt, Christoph; Gessner, Oliver; Vilesov, Andrey F.
    Lensless x-ray microscopy requires the recovery of the phase of the radiation scattered from a specimen. Here, we demonstrate a de novo phase retrieval technique by encapsulating an object in a superfluid helium nanodroplet, which provides both a physical support and an approximate scattering phase for the iterative image reconstruction. The technique is robust, fast-converging, and yields the complex density of the immersed object. Images of xenon clusters embedded in superfluid helium droplets reveal transient configurations of quantum vortices in this fragile system.
