Capture of negative muons in magnesium oxides and crystalline modifications of phosphorus

The paper is aimed at comparing the structure of mesic K X-ray patterns of phosphorus in its crystalline modifications, comparing the structure of mesic X-ray patterns of magnesium and oxygen in compounds of MgO, MgO2, H2O and metallic magnesium, as well as comparison of propabilities of μ- atomic capture in magnesium oxides. By analyzing the mesic K X-ray patterns of red and white phosphorus it is concluded that the phosphorus crystalline modification produces the effect on the line structure, the higher series number being somewhat larger for the allotrope of phosphorus with polymeric structure. A comparison is made of the mesic X-ray series of the magnesium in oxide and metal, of the oxygen in oxide and water with the analogous data for aluminium and silicon. The data confirm the supposition that chemical bond (valence electrons) plays a substantial role in meson capture
