Abstract

Abstract: Coulomb breakup reactions of $^{93, 94}$ Zr have been studied in inverse kinematics at incident beam energies of about 200 MeV/nucleon in order to evaluate neutron capture reaction methods. The $^{93}$ Zr(n, $\gamma$ )$^{94}$ Zr reaction is particularly important as a candidate nuclear transmutation reaction for the long-lived fission product $^{93}$ Zr in nuclear power plants. One- and two-neutron removal cross sections on Pb and C targets were measured to deduce the inclusive Coulomb breakup cross sections, 375 $\pm$ 29 (stat.) $\pm$ 30 (syst.) and 403 $\pm$ 26 (stat.) $\pm$ 31 (syst.) mb for $^{93}$ Zr and $^{94}$ Zr, respectively. The results are compared with estimates using the standard Lorentzian model and microscopic calculations. The results reveal a possible contribution of the pygmy dipole resonance or giant quadrupole resonance in the Coulomb breakup reactions of $^{94}$ Zr.
