The synthesis of 11B and 7Li via neutrino-induced nucleon emission (the {\\nu} -process) in supernovae is sensitive to the neutrino mass hierarchy for finite sin^2(2{\\theta}13) > 0.001}. This sensitivity arises because, when there is 13 mixing, the average electron neutrino energy for charged-current neutrino reactions is larger for a normal mass hierarchy than for an inverted hierarchy.
