Nonisotropic L-conversion-electron — X-ray directional correlations in160Dy

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The directional correlations betweenL-conversion electrons andL x-rays have been measured. The electrons were emitted in the 86.78keV 2+→0+ transition in160Dy, in the decay of160Tb. The experimental results areA 22(e L -x Li )=0.085 (22),A 22(e L -x Lα )=0.0066 (29),A 22(e L -x Lβ )=0.0000 (27), andA 22(e L -x Lγ )=0.0096 78). These results are in disagreement with published theoretical values. It is suggested that the discrepancy is due to a phase inconsistency in the internal conversion matrix elements and there is good agreement withA 22 values calculated in this work.
