L X-ray-gamma angular correlations following the decay of139Ce

Abstract

A reinvestigation of theL X-ray-gamma angular correlations following the decay of139Ce is made by using a Si(Li) semiconductor detector asL X-ray detector. Coincidence measurements at five different angles were made between the 166-keV gamma ray and theL X-ray spectrum. The data were handled in two different ways: (i) the counts under theL l +L α+L β+L γ peaks were taken; (ii) the counts under theL l +L α+L β peaks were only considered. Chance coincidences as well as coincidences background were taken into account.

The results indicate that no anisotropy is to be found within a margin of error of 6×10−3.
