Is (d,pγ) a surrogate for neutron capture?

To benchmark the validity of using the (d,pγ) reaction as a surrogate for (n,γ), the 171,173Yb(d,pγ) reactions were measured and compared with the neutron capture cross sections measured by Wisshak et al. The (d,pγ) ratios were measured using an 18.5 MeV deuteron beam from the 88‐Inch Cyclotron at LBNL. Preliminary results comparing the surrogate ratios with the known (n,γ) cross sections are discussed.
