“…Most important are however the g.s. and excited states at 0.067 and 0.283 MeV, within a first group, and at 0.656 and 0.909 MeV, within a second group, for which Zhang et al [97,98] measured α-particle angular distributions at neutron incident energies from 2.54 to 5.95 MeV. The same analysis as for 56 Fe and 59 Co is shown in Fig.…”

A consistent set of statistical-model input parameters, validated by analysis of various independent data, makes possible the assessment of an $$\alpha $$ α -particle optical model potential [Phys. Rev. C 90, 044612 (2014)] also for nucleon-induced $$\alpha $$ α -emission within the $$A \sim 60$$ A ∼ 60 mass-number range. The advantage of recent data for low-lying states feeding is taken as well. Consideration of additional reaction channels leading to increase of the $$\alpha $$ α -emission beyond the statistical predictions has concerned the pickup direct interaction and Giant Quadrupole Resonance similar features.

“…The analysis of α-particle emission in neutron-as well as proton-induced reactions has the advantage, for deexcitation of Zn isotopes, of accurate data at low incident energies [22,23,26,[96][97][98]. The α-particle OMP study becomes thus less dependent by NLD and PE effects.…”

“…The axis of the BF 3 long counter and the normal line of the electrodes of the gridded ionization chamber were at 0 • to the beam line. The distance from the cathode of the ionization chamber to the center of the neutron source was 15.4 cm, and that from the front side of the moderator of the BF 3 Experiments were performed in descending order of neutron energies of 6.0, 5.0, and 4.0 MeV. The electronics of the data-acquisition system was the same as in Ref.…”

Experimental cross section data of the 67 Zn(n,α) 64 Ni reaction are very scanty because the residual nucleus 64 Ni is stable and the commonly used activation method is not feasible. As a result, very large deviations (about 10 times) exist among different nuclear data libraries. In the present work, cross sections of the partial 67 Zn(n,α 0 ) 64 Ni and total 67 Zn(n,α) 64 Ni reactions are measured at neutron energies of 4.0 and 5.0 MeV for the first time, and those of 6.0 MeV are remeasured for consistency checking. A twin-gridded ionization chamber was used as the charged-particle detector and two enriched back-to-back-set 67 Zn samples were adopted. Experiments were performed at the 4.5 MV Van de Graaff Accelerator of Peking University. Neutrons were produced through the 2 H(d, n) 3 He reaction using a deuterium gas target. Absolute neutron flux was determined by counting the fission fragments from a 238 U sample placed inside the gridded ionization chamber while a BF 3 long counter was employed as neutron flux monitor. Present data are compared with results of previous measurements, evaluations, and TALYS code calculations.

Abstract. Cross sections of the 144 Sm(n,α) 141 Nd and 66 Zn(n,α) 63 Ni reactions were measured at E n = 4.0, 5.0 and 6.0 MeV performed at the 4.5-MV Van de Graaff Accelerator of Peking University, China. A doublesection gridded ionization chamber was used to detect the alpha particles. The foil samples of 144 Sm 2 O 3 and enriched 66 Zn were placed at the common cathode plate of the chamber. Monoenergetic neutrons were produced by a deuterium gas target through the 2 H(d,n) 3 He reaction. The neutron flux was monitored by a BF 3 long counter. Cross sections of the 238 U(n,f) reaction were used as the standard to perform the (n,α) reaction measurement. Present results are compared with existing measurements and evaluations. They are generally in agreement with TALYS-1.6 code calculations. For the 144 Sm(n,α) 141 Nd reaction our measurements support the data of JEF-2.2. For the 66 Zn(n,α) 63 Ni reaction present results support the data of EAF-2010 and TENDL-2015 data.
