“…[26], to reproduce calculations of exclusive neutron-removal cross sections based instead upon the microscopic G matrix interaction of Jeukenne, Lejeune, and Mahaux [27]. Most recently, this parameter choice has also been shown to reproduce the ratios of the diffraction and stripping mechanism yields, now measured precisely in 8 B and 9 C induced reactions by Bazin et al [28], and confirming an earlier but poorer statistics analysis by Enders et al [29].…”

“…Fast one-and two-neutron removal reactions from the neutron-rich carbon isotopes have been studied experimentally by several authors [8][9][10][11][12][13][14][15] 19 C (lower part). The energy intervals for transitions applicable to the inclusive cross sections for the indirect two-neutron removal (one-neutron removal followed by neutron emission), σ −1n(e) , and direct two-neutron removal, σ −2n(d) , reaction mechanisms are shown.…”

Reactions that involve the fast removal (knockout) of one and two neutrons from the neutron-rich carbon isotopes, 15−19 C, by light nuclear targets are studied within an eikonal reaction model. Shell model calculations are used to describe the excitation energy spectra and the structures of the carbon isotopes. The calculated one-neutron knockout cross sections from the A C isotopes, to particle-bound configurations of the A−1 C residues, are in agreement with the available experimental data. The two-neutron removal cross sections, producing A−2 C residues, receive contributions from both the direct, single-step two-neutron knockout and the indirect mechanism, involving single-neutron removal strength to neutron-unbound excited states in the A−1 C system followed by neutron emission. The latter two-step reaction mechanism is shown to be dominant. The empirical odd-even staggering of the single-neutron separation energies along the carbon isotopic chain is reflected in the two-neutron removal data. This staggering and the magnitudes of the two-neutron removal cross sections are reproduced qualitatively by the theoretical calculations.

“…Whereas in Fig. 2 (b) distinct evidence is presented to demonstrate the halo occurrences in 17 C and 19 C, i.e., more diffused neutron distributions with less neutrons than 22 C. In fact, the strong evidence of the halo occurrence in 19 C can be found from the parallel momentum distribution of 18 C after the breakup of 19 C [6]. As shown in Fig.…”

“…One of the representatives is the nuclear halo structure characterized by a dilute matter distribution contributed by several (in general two) loosely bound valence neutrons (or protons) surrounding a condensed core, which was first found in 11 Li [5]. As the typical light nuclei, the Carbon isotopes have been devoted many efforts to probing the possible halo structure [6][7][8] and specifically recent measured reaction cross section of 22 C [9] seems to assert a new two-neutron halo structure, which has also attracted fairly large interests from the community [10][11][12].…”

Description of carbon isotopes within relativistic Hartree-Fock-Bogoliubov theory

Within the relativistic Hartree-Fock-Bogoliubov (RHFB) theory, the structure properties of Carbon isotopes are systematically studied. To provide better overall description, the finite-range Gogny force D1S with an adjusted strength factor is adopted as the effective paring interaction in particle-particle channel. The selfconsistent RHFB calculations with density-dependent meson-nucleon couplings indicate the single-neutron halo structures in both 17 C and 19 C, whereas the two-neutron halo in 22 C is not well supported. It is also found that close to the neutron drip line there exists distinct odd-even staggering on neutron radii, which is tightly related with the blocking effects and correspondingly the blocking effect plays a significant role in the single-neutron halo formation.

Pairing correlations in odd-mass carbon isotopes and effect of Pauli principle in particle–core coupling in 13C and 11Be

et al. 2007

We present an exploratory study of structure of 13 C, 15 C, 17 C and 19 C, showing that the simple one-quasiparticle projected BCS (PBCS) model is capable to account for several important properties of these nuclei. Next we discuss the importance of the Pauli Principle in the particle-core models of normal-parity states in 13 C and 11 Be. This is done by considering the pairing interaction between nucleons moving in an over-all deformed potential. To assess the importance of pairing correlations in these light nuclei we use both the simple BCS and the PBCS approximations. We show that the Pauli Principle plays a crucial role in the parity inversion in 11 Be. It is also found that the effect of the particle number conservation in relatively light and/or exotic nuclei is quite significant. Comparison of our results with several recent papers on the same subject, as well as with some experimental data, is presented.
