Abstract
The neutron total and capture cross sections of 92,94Zr have been measured at the 80 and 40 m flight stations, respectively, on the Oak Ridge Electron Linear Accelerator (ORELA). Resonance analysis of the total cross sections gave values of s, p 3 2 and p 1 2 strength functions. Strong intermediate structure was observed in the p 3 2 cross section of 92Zr. Significant single particle transitions identified in the p-wave capture cross section indicate the importance of the valence process for both nuclei. It is noted that the intermediate structure in the p 3 2 total cross section leads to enhanced valence effects in the capture cross section. The effects of non statistical E1 transitions following particle-hole annihilation in the compound states were not observed in either the 92Zr or 94Zr capture cross sections as they had been in that for 90Zr.
