Effect of hexadecapole deformations on i orbits and pickup cross sections in the tungsten nuclei

Previous (d,t) and (τ,α) cross sections to 13 2 + states in odd-mass tungsten nuclei have been interpreted in terms of moderate hexadecapole deformations (ϵ4≈0.06) while a recent Coulomb excitation measurement has suggested a much larger value for 182W. We have calculated the pickup spectra and show that in fact the data can be successfully interpreted with a wide range of ϵ4 values from ≈0.06 to ≈0.16.
