Theoretical research on proton halos in exotic nuclei

Abstract: Very neutron-deficient nuclei are investigated with Woods-Saxon potentials, especially the newly measured A=2Z–1 nucleus 65As [X.L. Tu et al., Phys. Rev. Lett. 106, 112501 (2011)], where the experimental proton separation energy is obtained as -90(85) keV for the first time. Careful consideration is given to quasibound protons with outgoing Coulomb wave boundary conditions. The observed proton halos in the first excited state of 17F and in the ground states of 26,27,28P are reproduced well, and predictions of … Show more

“…In contrast to those of 27 P/ 27 Mg [31,32] and 28 P/ 28 Al [23], an unusually large mirror asymmetry δ = 51(10)% in the 26 P/ 26 Na GT β-decays was recently reported by Pérez-Loureiro et al [21] (previously measured as δ = 50(60)% in [22]). Combining with the nearly-vanishing proton separation-energy of 0(90) keV, the authors in [21] interpreted the abrupt enhancement in δ at A = 26 as a signature for a proton halo in 26 P. The proton halo in 26 P was later studied theoretically by Ni and Ren [38]. The radial wave function of the proton s 1/2 orbit in the parent nucleus can have a very long tail, owing to the lack of the centrifugal barrier [39], and thus can extend into a space much larger than that of other orbitals.…”

“…With the continuous developments of radioactive beam facilities, the study of exotic nuclei far from the β-stability line has became a hot project in nuclear physics field [1][2][3][4][5][6][7][8][9]. Exotic nuclei usually exhibit distinctive features that can provide a lot of information about the nuclear structure different from the well-known stable nuclei, such as new shell closures [10], coupling of bound state and unbound state and so on [11].…”

“…In recent years, the study of exotic nuclei far from the β-stability line has became an interesting topic in nuclear physics with the developments of radioactive beam facilities [1][2][3][4][5][6][7]. Two-proton (2p) radioactivity, as an important exotic decay mode, provides a new way to obtain the nuclear structure information of rich-proton nuclei [8][9][10].…”
