However, it is difficult - if not impossible - to directly measure neutron capture cross sections for the exotic, short-lived nuclei that participate in these processes. In this Letter we demonstrate a new technique which can be used to indirectly determine neutron-capture cross sections for exotic systems. This technique makes use of the $(d,p)$ transfer reaction, which has long been used a","authors_text":"A. Ratkiewicz, B. Manning, C. Shand, G. Potel, J. A. Cizewski, J. E. Escher, J. T. Burke, K.
