Experiments related to X-ray optics carried out by A. H. Compton and hiscollaborators during 1923-1927, led to the Nobel Prize winning discovery ofCompton Effect. Based on the critical analyses of these experimentalinvestigation results, we could infer a unique X-ray reflection property ofspeculum metal that provided us the evidence for its reflectivity in the hardX-ray region. In connection with this, we have studied in detail thetheoretical X-ray reflectivity of speculum metal in comparison with variety ofother mirror materials for different photon energies at various grazing anglesof incidence. Theoretical calculations of grazing incidence X-ray reflectivityfor these materials also verified well with other experimental data andcomputer simulations. We have also calculated the minimum and critical anglepenetration depth of speculum metal with other mirror materials for differentphoton energies. Furthermore, the reflectivity of speculum metal in differentregions of electromagnetic spectrum in association with its physical propertiesis discussed. The analytical results obtained from these studies indicated thatthe reflectivity of speculum metal in the X-ray region, especially in hardX-ray region at small grazing angles is higher than that for commonly used highdensity mirror materials.
