Gamma-ray-L-x-ray directional correlations in182W

Abstract

Directional correlations between gamma radiation and L x-rays in 182W have been measured. The x-rays are emitted following the internal conversion process of the 100.1 keV 2 + ~ 0 + transition. The experimental results for anisotropies involving gamma radiation emitted in the 1189.0 keV transition and L x-rays are A(7-Lt)=-0.073(27), A(7-L~)=-0.0102(45), A(y-Lp)=-0.0031(35), and A(y-L~)=--0.007(13). The value deduced for the coefficient U2(e) pertaining to the converted transition is U2(e)=0.52 (8) in reasonable agreement with the theoretically expected value 0.410. A note is given on the use of internal conversion radial matrix elements.
