Intensity Patterns of Pionic X Rays Emitted from Some Organic Compounds

Abstract

Pionic atom / Pionic X rays / Negative pion transfer process / Cascade calculation / Pionic hydrogen atom SummaryPionic X-ray intensity pattems of the Balmer series have been studied in the carbons and oxygens of alcohols, carboxylic acids, alkanes, etc. The X-ray intensity ratios (4-2)/(3-2) in the carbons of both alcohols and carboxylic acids decrease with the number of carbon atoms and approach that of Polyethylene. On the other hand, the ratios in oxygen remain constant. The variations in the intensity ratios are discussed based on a pionic cascade calculation. The results of the calculation show that the differences in the intensity pattems are attributed to both the differences in the chemical bond lengths and the contribution of pion transfer from the pionic hydrogen.

Chemical effect on muonic atom formation through muon transfer reaction in benzene and cyclohexane samples

“…Shinohara et al [29] reported that the pion capture probability of hydrogen atoms of hydrocarbon molecules varied with the molecular structure. Furthermore, they reported that the pionic X-ray intensity pattern of the Balmer series varied with the molecular structure of hydrocarbon molecules [30]. For condensed systems, they reported the chemical effect on the pion transfer reaction in mixtures of carbon tetrachloride and benzene or cyclohexane [31].…”
