DOIAbstract
Relative yields of fragments following the 78Kr projectile fragmentation in a beryllium target were measured in a storage ring by using isochronous mass spectrometry (IMS). Odd–even staggering of the relative fragment yields is observed and can be explained by the odd–even staggering of the particle-emission threshold energies. IMS is a complementary technique to γ-ray spectroscopy for measuring isomeric ratios, in particular for nuclides with long lifetimes. It was found that the isomeric yield ratios in 53Fe are almost constant for different longitudinal momenta
