CERN Accelerating science

In this contribution results will be reported from two recent experiments at the GSI Fragmentseparator (FRS). The first experiment is using one‐nucleon knockout with relativistic fragments from a 500 AMeV 
86
Kr
 primary beam to probe the single‐particle structure in 
49
Ca
 and 
55
Ti
.
 From the one‐neutron knockout in the neutron‐rich nuclei 
50
Ca
 and the 
N
 = 34
 nucleus 
56
Ti
 cross sections and momentum distributions were deduced allowing the determination of angular momentum values and spectroscopic factors for individual states.

In the second experiment decay spectroscopy of 
100
Sn
 and nuclei in its vicinity was performed. The nuclei of interest were produced using the fragmentation of a 1 AGeV 
124
Xe
 primary beam. The RISING gamma‐ray detector array was used in close geometry to detect gamma‐decay following isomeric as well as beta decays. Aside from the production of more that 200 
100
Sn
 nuclei, several new isotopes and isomers were discovered.
