Recently, level lifetimes in the stable Zr nuclei have been measured by our group using the Doppler-shift attenuation method following inelastic neutron scattering. This study revealed that the published level lifetime data for 94Zr were in error; the source of the discrepancy was investigated thoroughly as described in Ref. [1] and is attributed to the chemical properties of the enriched zirconium (IV) oxide, 94ZrO2, scattering sample utilized for the measurements. While many of the level lifetimes were remeasured, the new measurements were completed using metallic Zr and ZrO2 samples of natural isotopic abundance, which prevented the measurement of all of the lifetimes in
94Zr which were previously obtained. Some γ rays become obscured by those originating from other Zr isotopes or the statistical quality for weak γ rays is too poor to obtain a reliable measurement in a practical time period due to the small amount of 94Zr present (17.38% natural abundance) in the sample. Thus, a correction method was developed and is also detailed in Ref. [1]. Table I is a reproduction of Table II in the original paper but containing the corrected level lifetimes from Ref. [1].
