determined experimentally. The irradiations were performed near the core of the IEA-R1 3.5
MW nuclear research reactor of the Nuclear and Energy Research Institute–IPEN-CNEN/SP,
in São Paulo, Brazil. The results for the neutron field parameters f and α were 49.7 (19) and−
1.1 (31)× 10− 3, respectively. The resulting values of k 0 and Q 0 for 64 Zn (n, γ) 65 Zn
reaction were 5.63 (8)× 10− 3 and 1.69 (6), respectively, and the corresponding values for …
