164Ta, identification of a new isotope

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The new isotope164Ta (T 1/2=13.6(2)s) was produced in the127I(40Ca, 3n) reaction and transported to a measuring station by helium jet. Decay properties were observed withα, γ, andγ-γ spectroscopy. TheZ assignment of the new isotope was based ongg-X-ray coincidence measurements. The mass assignment was deduced from measured excitation functions. The twoγ rays assigned to the new activity most likely originate from the 4+→2+→0+ decay sequence in164Hf. A smallα branch, ≦0.016(5)%, with anα decay energy ofE α=4,625(15) keV was found and assigned to the decay of164Ta. The deduced upper limit of theα width for this branch,W α≦0.6(2), is in accordance with those known for neighbouring nuclei.
