Gamma-Rayand Conversion-Electron Spectroscopyof Exotic Heavy Nuclei

Progress in the conceptual design of future gamma-tracking arrays with imaging capabilities. Lifetime measurement in neutron-rich nuclei in the region of the double magic Ni with the AGATA demonstrator

“…Because of the experiments proposed for DESPEC and the two operational modes of the Super-FRS: achromatic or monochromatic, the ion implantation in the AIDA plane will not be homogeneous. To evaluate the basic benefits for the different geometries, the most relevant parameters are the peak efficiency and the P/T ratio, therefore, mean values of these parameters ((ε p ) and (P/T )) have been calculated in a surface of 22*6 cm 2 of the AIDA central slide since in this region ions will be implanted with higher probability ( Table 2. 5). Other important parameters that should be considered in the choice of the 2.5 Performance study of the DESPEC Ge array 41 array geometry are the number of electronic channels and the amount of Ge employed in the design, because they are directly related to the cost of the system.…”

“…With this method a P/T of 50% can be obtained. Figure 1.1: a) Anti-Compton detector surrounding the Ge detector with the aim of suppress the partially absorbed events in the spectra; b) detector composed by different Ge crystals that allows to add the signals; c) segmented detector that allows the reconstruction of the individual trajectory of γ rays [5].…”

“…5: Q values of the proton stripping and neutron striping or pickup channels for the previous experiment ( 70 Zn + 238 U) and for the present one ( 76 Ge + 238 U) to be compared. Cross sections and number of counts obtained in the 70 Zn (460 MeV) + 238 U experiment performed at LNL used for the comparison with the current experiment,76 Ge (500 MeV) + 238 U.…”
