Energy levels of136Pm and136Nd via beta decay of136Sm and136Pm

  • Published:
Zeitschrift für Physik A Atomic Nuclei

Abstract

136Pm and136Nd were studied using theβ decay of136Sm and136Pm. The radioactive nuclei were produced by the92Mo (48Ti,xpyn) and112Sn (28Si,xpyn) reactions. The UNISOR isotope separator enabled mass identification. The previously unknown level scheme of136Pm was constructed and the half-life of136Sm was determined to be 47±2 s. Six new levels and thirteen newγ-ray transitions have been added to the level scheme of136Nd.
