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 T_r 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 T_r is given.
