High precision γ spectroscopy of 69,71Zn from (n, γ) reactions using EXILL

Measurement of γ radiation following slow neutron capture on 68 Zn and 70 Zn using very efficient germanium array EXILL was done at Institute Laue-Langevin in Grenoble. New spectroscopic information for 69 Zn (including doorway state) and first results for 71 Zn (accurate energy of β decaying isomer) were obtained. Binding energies for 68 Zn, 69 Zn and 71 Zn were determined with 5-to-70 times higher accuracy than presented in the literature.
