Annihilation of a relativistic positron and K-electron to yield a photon and second K-electron
Journal of Experimental and Theoretical Physics, 1998We study the annihilation of a fast positron and a K-electron resulting in the emission of a photon and a second K-electron. It is assumed that all electrons and positrons move in the Coulomb field of the nucleus and that the Coulomb parameter αZ is much less than unity (α=1/137 is the fine-structure constant and Z is the atomic number).

K-electron capture probabilities in161Ho
Il Nuovo Cimento A, 1993TheK-electron capture probabilities for the 7/2−→7/2− and 7/2−→5/2− transitions in161Ho were measured for the first time using the X-γ sum peak method. The correspondingPK values were found to be 0.836±0.042 and 0.814±0.023, respectively, in agreement with the theoretically predicted values.

Polarization effects in Compton scattering from K-electrons
Radiation Physics and Chemistry, 2004The triply differential cross section (TDCS) for Compton scattering from K-electrons is obtained in a full relativistic second-order S-matrix numerical calculations within the independent particle approximation (SM). The approach is applicable in all three regions of the Compton spectrum: the infrared divergent region, the resonant region and the ...
