Studies on the decays of 153Sm and 153Gd to 153Eu

Abstract

The relative intensities of x-rays and gamma rays emitted in the decays of ¹⁵³Sm and ¹⁵³Gd have been measured precisely using a set of five HPGe and Si(Li) detectors. The intensities of L x-rays from ¹⁵³Gd and K and L x-rays from ¹⁵³Sm decays have been measured for the first time. In addition, the level scheme of ¹⁵³Eu following ¹⁵³Sm decay was also investigated using high resolution HPGe-HPGe coincidence set-up (2τ = 7 ns).
