212Th, a new isotope

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The new isotope212Th has been found to decay withE α = (7.802 ±0.010) MeV andt 1/2 =(30 +20−10 ms. The decay energies of the previously observed isotopes213Th and214Th could be confirmed. The measured half-lives are in agreement with calculated values.
