Consistent optical potential for incident and emitted low-energy alpha particles. II. alpha emission in fast-neutron-induced reactions on Zr isotopes

摘要

Background: Challenging questions of the alpha-particle optical-model potential (OMP) are still pointed out by recent high-precision measurements of alpha-induced reaction data below the Coulomb barrier. Moreover, the reliability of a previous OMP for alpha particles on nuclei within the mass number range 45 <= A <= 209 has been recently proved for emitted alpha particles as well, but only in the case of proton-induced reactions on Zn isotopes [Phys. Rev. C 91, 064611 (2015) (Paper I)].
