Abstract
The authors demonstrate that if one is willing to focus only on the coarser aspects of p(H) (the detailed shape of the hyperfine field distribution), such as its mean and its variance, then the Mossbauer spectra can be analysed consistently in a manner which retains all relevant parameter correlations even if no analytic relationships exist between the parameters. Measurements of room-temperature Mossbauer Zeeman spectra are reported for six different boron and phosphorus metalloid glasses and are analysed in this fashion. Complete results for mean values and variances of hyperfine fields, isomer shifts and pure quadrupole distributions are tabulated, the last two variances being reported for the first time in a ferromagnetic phase.
