Ein internationales Forscherteam hat mit dem weltstärksten Röntgenlaser Schnappschüsse freier Moleküle gewonnen. Die Wissenschaftler um Prof. Jochen Küpper vom Hamburger Center for Free-Electron Laser Science (CFEL) haben dazu eine Art Molekülballett im Röntgenstrahl choreographiert. Mit ihrer Arbeit nehmen die Forscher wichtige Hürden auf dem Weg zu Röntgenbildern individueller Moleküle, wie sie im Fachblatt "Physical Review Letters" erläutern. Das CFEL ist eine gemeinsame Einrichtung von DESY, der Universität Hamburg und der Max-Planck-Gesellschaft.
"Uns sind die ersten Röntgenlaseraufnahmen eines Ensembles isolierter Moleküle gelungen", sagt DESY-Forscher Küpper, der auch Professor an der Universität Hamburg sowie Mitglied des Exzellenzclusters Hamburg Centre for Ultrafast Imaging (NXT) lto.
