Stretched states in B 12,13 with the (d,α) reaction
The (d,α) reaction is highly selective, favoring final states in which the removed neutron and proton are completely aligned in a J=2j configuration. We have studied the C14,15(d,α)B12,13 reactions in inverse kinematics using the Helical Orbit Spectrometer (HELIOS) at Argonne National Laboratory. In B12, the reaction strongly favors the population of a known 3+ state at 5.61 MeV, and for B13, we observe a possible unreported doublet of states at high excitation energy, probably corresponding to the B12(3+) state coupled to the 1s1/2 neutron from the C15 ground state. In contrast to single-nucleon transfer, deuteron-transfer reactions have not been widely studied with exotic nuclei.
