Theory of coherent phenomena and fundamentals in nuclear resonant scattering

Muonic X-ray cascades in B, C, N, O and Ne following muonic atom formation in B₂H₆, CH₄, C₂H₆, C₄H₁₀, N₂, O₂ and Ne were investigated. The densities of the different target gases were low enough to prevent any contact of the atom or molecule on which the formation takes place with surrounding atoms or molecules during the cascade. Molecular effects of the capturing molecule are clearly seen. The observed transition yields could be reproduced by variation of only two parameters in a cascade calculation: the number of initially available electrons and the muon angular momentum distribution at the starting point of the calculation. By varying the number of electrons, the molecular effects could be described. This revised version was published online in August 2006 with corrections to the Cover Date.
