Precise measurement of the energy of γ rays excited in 191Pt decay

Abstract

The energy differences for 19 pairs of γ rays are measured with a γ spectrometer. The first γ transition in each pair is excited in decay of 191Pt, and the second transition, accompanying the decay of 182Ta or 192Tr is a third-order nuclear spectroscopic normal. The energies of nine 191Ir levels and 36 γ-ray photons accompanying decay of 191Pt, were determined with high accuracy on the basis of these data.
