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

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