Electron Screening in Metals — •Francesco Raiola, Claus Rolfs, and Frank Strieder — Institut für Experimentalphysik III, Ruhr-Universität Bochum
Recently, the electron screening effect on the d(d,p)t reaction has been studied in the metals Al, Zr, and Ta, where deuterated metals were produced via implantation of low-energy deuterons. The resulting S(E) data show the well known exponential enhancement, however the extracted electron screening potential values Ue are one order of magnitude larger than the values found in the corresponding gas-target experiment as well as that predicted from the adiabatic limit. In a new measurement at the 100 kV accelerator at the Ruhr-Universität Bochum the observation of the large electron screening effect in the d(d,p)t reaction using a deuterated Ta target has been confirmed using somewhat different experimental approaches. Studies using other deuterated metals are on the way and new results will be presented in this talk.
