$sideset{^{179}}{}{mathop { m ta}}(n,gamma$) cross-section measurement and the astrophysical origin of the $sideset{^{180}}{}{mathop { m ta}}$ isotope

HIGHLIGHTS

SUMMARY

References suggest that 180 Ta is produced by 180 Hf (νe, e) 180 Ta and 181 Ta(ν, ν n) 180 Ta reactions in the ν process in stellar explosions. A direct measurement of 179 Ta(n, γ ) cross section at neutron energies relevant to s-process temperatures (keV neutron energies) has not been possible yet due to the lack of availability of a radioactive 179 Ta (T1/2=1.82 y) target with sufficient mass. The larger neutron fluxes available at research reactors allow an activation measurement of the 179 Ta(n, γ ) 180 Ta reaction at thermal . . .
