Anisotropy of L X-rays of Uranium and Thorium

INTRODUCTION

The theoretical calculations by Flugge et a1 l] have shown that the Xrays originating from the states corresponding to J=1/2(K shell and L_I, L_II, M_I, M_II subshell etc.) are emitted to be isotropic and those corresponding to state J=5/2(e.g. Mv subshell) are emitted to be anisotropic in their spatial distribution. There are many studies on L X-ray intensity ratios. But there is little reported on isotropy and anisotropy of L X-rays. Kahlon et a1 2,3] investigated isotropy and anisotropy of L X-rays. We investigated the anisotropy of L shell X-rays in Au and Hg 4] and the angular dependence of differential cross-sections of L X-rays from Hg, T1 and Pb 5].
