Wie entstehen freie Elektronen?

Neue Erzeugungsart langsamer Elektronen nachgewiesen / Erklärung für biologische Strahlenschäden?

(PresseBox) (Garching, )
Einen bisher unbekannten Weg, auf dem energiereiche Strahlung in Wasser langsame Elektronen freisetzen kann, haben Wissenschaftler des Max-Planck-Instituts für Plasmaphysik (IPP) in Garching/Greifswald und des Fritz-Haber-Instituts in Berlin entdeckt. Die Ergebnisse wurden jetzt in dem renommierten Fachblatt "Nature Physics" publiziert. Freie Elektronen spielen eine große Rolle bei chemischen Prozessen. Insbesondere könnten sie für das Entstehen von Strahlenschäden in organischem Gewebe Bedeutung besitzen.

Trifft ionisierende Strahlung auf Materie, dann werden stets große Mengen langsamer Elektronen freigesetzt. Bisher nahm man an, dass diese Elektronen durch die energiereiche Strahlung aus der Elektronenhülle der getroffenen Teilchen - etwa aus einem Wasser-Molekül - herausgeschlagen werden.
