Abstract

Isotopic production cross sections were measured for proton- and deuteron-induced reactions on ⁹³Nb by means of the inverse kinematics method at RIKEN Radioactive Isotope Beam Factory. The measured production cross sections of residual nuclei in the reaction ⁹³Nb + p at 113 MeV/u were compared with previous data measured by the conventional activation method in the proton energy range between 46 and 249 MeV. The present inverse kinematics data of four reaction products (⁹⁰Mo, ⁹⁰Nb, ⁸⁸Y, and ⁸⁶Y) were in good agreement with the data of activation measurement. Also, the model calculations with PHITS describing the intra-nuclear cascade and evaporation processes generally well reproduced the measured isotopic production cross sections.
