Abstract:
The yield has been determined for the excitation
of the 180gTa (Jπ=1+) from the
181Ta(γ, n) reaction by measurements of the γ
rays emitted following the electron capture and beta-decays of the
8.15 h ground state. The probability of (σm/(σm+σg)
for the production of the 180mTa Isomer (jπ=9-)
after γ absorption in the energy region from 8 to 13 MeV was
deduced. The role of the initial and final spins on the reaction yield,
along with the relevance of necleosynthesis of 180mTa,
is discussed.
