Spectroscopy of neutron-rich 59-63Mn isotopes

The neutron-rich Mn isotopes from A = 59 to 63 have been studied through multi-nucleon transfer reactions by bombarding a U-238 target with a beam of Zn-70 at an energy of E-lab = 460 MeV. Prompt gamma rays measured by the CLARA array have been identified unambiguously for each nucleus, using coincidence relationships with ions detected in the high-acceptance magnetic spectrometer PRISMA. The new data extends the knowledge of the low-lying level structure of Mn isotopes, which is discussed in terms of the systematics of the region. Results are compared with large-scale shell-model calculations using different effective interactions and valence spaces.
