“…For ordinary (nonhalo) nuclei, this value would have been about σ~100MeV/c. The small width of the momentum distribution confirms the presence of halo in 6 He [12,13]. Intermediate width of the momentum distribution supports hypothesis of n-p halo of tango type in 6 Li g.s.…”

Abstract. Structure of the ground and excited states in halo-like nuclei is discussed. Both the Borromean and tango halo types can be observed for n-p configurations of atomic nuclei.Structure of the halo may be different for the different levels and resonances in atomic nuclei. Isobar analog, double isobar analog, configuration, and double configuration states can simultaneously have n-n, n-p, and p-p halo components in their wave functions. When the halo structure of the excited state differs from that of the ground state, or the ground state has non-halo structure, the γ-transition from the excited state to the ground state can be essentially hindered, i.e. the formation of a specific type of isomers (halo isomers) becomes possible. B(Mλ) and B(Eλ) values for γ-transitions in 6

“…The momentum distributions of 4 He from the 6 He and 6 Li breakup were measured for different targets and beam energies. The observed momentum distributions are narrow for the 6 He breakup (σ=28−29MeV/c) and intermediate for the 6 Li breakup (σ=46−55MeV/c) [12,13]. For ordinary (nonhalo) nuclei, this value would have been about σ~100MeV/c.…”

“…The (α + d)-cluster structure of 6 Li should result in a large breakup yield of these fragments. Besides, it is established that the 3.56 MeV 0 + -state of 6 Li has a halo-like structure formed by a proton plus a neutron [16,17]. It is the isobar analog of the 6 He ground state and is situated only 136 keV below the threshold for the three-particle decay 6 Li → α + p + n (3.699 MeV) [15].…”

Experimental excitation functions are presented for fusion-evaporation and transfer reactions in the interaction of 6 Li with Bi and Pt targets. The data on the cross sections obtained for the produced evaporation residues are in agreement with calculations within the framework of the statistical model using the ALICE-MP code. Enhancement of the cross section for deuteron transfer reactions is observed at energies below the Coulomb barrier. The results are discussed from the point of view of how the nuclear cluster structure influences the probability of interaction at near-barrier energies.
