Study of gamma ray transitions and level scheme of Mn2556 using the Mn2555(n<inf>th</inf>,2γ) reaction

Abstract

© 2019 This work provides new data about the level scheme of Mn2556 studied by the Mn2555(nth,2γ) reaction. The spectroscopic information were collected using the gamma-gamma coincidence spectrometer at the Technische Universität München, Heinz Maier-Leibnitz Zentrum (MLZ), Garching, Germany. The intensities, energies of primary and secondary transitions of 71 energy-resolved cascades, as well as intermediate cascade levels were determined. The updated level scheme of Mn2556 was obtained from analyzing the intensity spectra of the strongest cascades. The comparison with the existing data in the ENSDF database shows that 23 primary transitions, 24 intermediate cascades levels as well as 32 secondary transitions determinated in this work can be recommended as new nuclear data.
