Abstract

A γ-source based on the Cr(n, γ) reaction is utilized for studying the resonance scattering from the 7362 keV level in 68Zn. It is shown that at room temperature the resonance scattering cross section may vary by about 5% by merely changing the atomic environment of the scatterer. At T = 20 K, variations of around 15% may be achieved. This is explained in terms of the different Doppler broadenings of the nuclear level caused by different atomic binding. The effective temperatures Tr of the Zn atom in various chemical forms such as metallic Zn, ZnS and ZnO were measured. A prescription for reproducing the measured values of Tr is given.
