被引用回数:24 パーセンタイル:85.45(Instruments & Instrumentation)In the last years, the new gas-filled TransActinide Separator and Chemistry Apparatus (TASCA) was installed and successfully commissioned at GSI. Here, we report on the design and performance of a Recoil Transfer Chamber (RTC) for TASCA, which is an interface to connect various chemistry and counting setups with the separator, as well as measurements of the transportation yields under various conditions and on the first chemistry experiments at TASCA - an electrochemistry experiment with osmium and an ion exchange experiment with the transactinide element rutherfordium.

被引用回数:107 パーセンタイル:97.51(Physics, Nuclear)We have investigated the isoscalar giant resonances in the Sn isotopes using inelastic scattering of 386-MeV particles at extremely forward angles, including 0. The strength distributions for various multipoles were extracted by a multipole decomposition analysis based on the expected angular distributions of the respective multipoles. We find that the centroid energies of the isoscalar giant monopole resonance (ISGMR) in the Sn isotopes are significantly lower than the theoretical predictions. In addition, the asymmetry term, , in the expression for the nuclear incompressibility has been determined from the ISGMR data in Sn isotopes and is found to be consistent with a number of indirectly extracted values for this parameter.
