A lower limit of 0.63 ± 0.02 b has been determined for the thermal neutron capture cross section (σ0) of 93Zr from a measurement of the prompt γ-rays emitted by the 93Zr (n th,γ) 94Zr reaction. The present result for 93Zr is much smaller than the single previously reported measurement as well as compiled and evaluated values for this cross section. This work also reports a lower limit for σ0 of 91Zr as 1.30 ± 0.04 b, which is consistent with the single previously reported measurement, as well… 
Cross section measurement of residues produced in proton- and deuteron-induced spallation reactions on 93Zr at 105 MeV/u using the inverse kinematics method
Isotopic production cross sections in the proton- and deuteron-induced spallation reactions on 93 Zr at an energy of 105 MeV/u were measured in inverse kinematics conditions for the development of
Measurements of gamma-ray emission probabilities in the decay of americium-244g
ABSTRACT Accurate data of gamma-ray emission probabilities are frequently needed when one quantitatively determines the amount of isotope by gamma-ray measurements or obtains neutron capture
Study of proton- and deuteron-induced spallation reactions on the long-lived fission product 93Zr at 105 MeV/nucleon in inverse kinematics
93 Zr have been studied in order to provide basic data necessary for nuclear waste transmutation. Isotopic-production cross sections via proton- and deuteron-induced spallation reactions on 93 Zr at

Neutron capture measurements on radioactive93Zr
Neutron capture measurements made on a sample of fission-product zirconium containing 20%93Zr(t1/2=1.5×106a) at the Oak Ridge Electron Linear Accelerator time-of-flight facility resulted in the
Neutron Transmission Measurement and Resonance Analysis of 93Zr from 60 to 6000 eV
Neutron transmission through a zirconium oxide sample containing the radioactive /sup 93/Zr isotope was measured by pulsed neutron time of flight. R matrix parameters for some of the resonances up to
Experimental and theoretical values of thermal neutron captare cross- sections were compared for a number of cases. An attempt is made to explain the discrepancy in many cases. It is proposed that in
