The Rare ISotopes INvestigation (RISING) project combines the FRagment Separator(FRS) at GSI with a high-efficiency Germanium array. The project focuses on studies of shell evolution far off stability, pn-pairing, symmetries and nuclear shapes utilising projectile fission and fragmentation beams.
The Germanium setup has been used in three different geometries, optimized for stopped beams, g-factor measurements and scattering experiments at relativistic energies. The stopped beam setup provides the highest absolute photo-peak g-efficiency of 15% at 1.3 MeV, and was used for isomer and beta decay studies.
Since 2003 the RISING collaboration obtained numerous experimental results[1]. The successful experimental program promoted the development of the HISPEC/DISPEC project [2], which is planed for the future FAIR/NUSTAR facility [3].
Highlights of resent results obtained with the RISING stopped beam setup along the N=Z line and the structure of the N=126 isotones will be presented. An overview of the current development and the future plans for HISPEC/DISPEC will be discussed .
