Mass measurements of the $^{69}$As, $^{70,71}$Se and $^{71}$Br isotopes, produced via fragmentation a $^{124}$Xe primary beam at FRS GSI, have been performed with multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) Ion Catcher an unprecedented resolving power almost 1,000,000. For $^{69}$As isotope, this is first direct measurement. A uncertainty 22 keV was achieved only 10 events. $^{70}$Se 2.6 obtained, corresponding to relative accuracy $\delta$m/m = 4.0$\times 10^{-8}$, less...
Direct mass measurements of neutron-deficient nuclides around the $N=50$ shell closure below $^{100}$Sn were performed at FRS Ion Catcher (FRS-IC) GSI, Germany. The nuclei produced by projectile fragmentation $^{124}$Xe, separated in fragment separator and delivered to FRS-IC. masses 14 ground states two isomers measured with relative uncertainties down $1\times 10^{-7}$ using multiple-reflection time-of-flight spectrometer FRS-IC, including first direct $^{98}$Cd $^{97}$Rh. A new...
We present first preliminary results of a novel method for measuring independent isotopic fission yields (IIFYs) spontaneous (SF) via direct mass measurements, at the FRS Ion Catcher (FRS-IC) GSI. Fission products were generated from 252 Cf source installed in cryogenic stopping cell, and identified counted with multiple-reflection time-of-flight spectrometer (MR-TOF-MS) FRS-IC, utilizing well-established measurement data analysis methods. The MR-TOF-MS resolves isobars unambiguously, even...
The 'island' of fission isomers identified in the actinide region (Z = 92 - 97, N 141- 151) originates from multi-humped barriers, which can be described as result superimposing microscopic shell corrections to macroscopic liquid drop barrier. For first time, populating by using fragmentation 1 GeV/u $^{238}$U projectiles was tried rather than light particle induced reactions so far use. Projectile gives access isotopes that are hard or impossible reach reactions. In-flight separation with...
At the FRS Ion Catcher (FRS-IC), projectile and fission fragments are produced at relativistic energies, separated in-flight, energy-bunched, slowed down, thermalized in ultra-pure helium gas-filled cryogenic stopping cell (CSC). Thermalized nuclei extracted from CSC using a combination of DC RF electric fields gas flow. This also serves as prototype for Super-FRS, where exotic will be unprecedented rates making it possible to go towards extremes nuclear chart. Therefore, is essential...
