Abstract

The behavior of ⁵⁷Fe and ⁵⁷Co doped β‐rhombohedral boron was investigated by means of Mössbauer spectroscopy. Samples prepared by diffusing ⁵⁷Fe at temperatures above 1000 °C and ⁵⁷Co at temperatures of 1500 °C or higher showed a reproducible quadrupole interaction and a strongly anisotropic ƒ‐factor. Using combinations of the different parameters obtained from the spectra it was attempted to determine the position of the impurities. There is some evidence for an incorporation within the 28 atom subgroup. It was shown that the sites occupied by Co and Fe do not have a C_{5 v} point symmetry.
