Molecular effects in pion capture in complex materials

Abstract

Intensities of X rays from pionic atoms in various materials determine the pion capture ratio in carbon and oxygen. A molecular model with transfer from hydrogen has the features necessary to fit the data whereas the Fermi–Teller law (Z-law) fails. Implications for pion dosimetry and radiotherapy and for studies of molecular structure are noted.
