Investigation of Angular Distribution of K shell X rays - a New Approach

Abstract

Measurement of differential K shell X-ray intensity ratios,  for copper and gadolinium at 60^o-100^o has been reported. A new approach has been developed to know quantitatively the isotropy in K shell X-rays. The present results confirm the prediction of the calculations of Flugge et al.¹, Scofield², Berezhko et al.³ and Cooper and Zare⁴ that, after photoionization of inner shells, the vacancy states with J = 1/2 has equal population of magnetic sub states and the subsequent K shell X-ray emission is isotropic.
