Possible neutron and proton halo structure in the isobaric analog states of A=12 nuclei

NUCLEAR REACTIONS ¹¹B(³He, d)¹²C, E=25 MeV from K130 cyclotron of University of Jyvaskyla; measured E(d), I(d), σ(θ) using three sets ofDE-E silicon and Si(Li) detector telescopes. ¹²C; deduced levels, IAS, J, π, proton halo in the corresponding IASs of ¹²N from MDM analysis; analyzed a triplet of IASs with isospin T=1 in ¹²B, ¹²C, and ¹²N nuclei and compared their rms radii. Comparison with theoretical calculations in the framework of coupled-reaction channels (CRC) method for direct proton transfer to the bound and unbound states using the code FRESCO.
