“…The measurement of 10Be + p elastic resonance scattering was carried out at the Heavy Ion Research Facility in Lanzhou (HIRFL) [28,29], China. A secondary ion beam of l0Be was produced by the Radioactive Ion Beam Line in Lanzhou (RIBLL) through the projectile fragmentation of a 59.62A MeV lsO primary beam with an average intensity of 100 enA bombarded on a solid 853.96-mg/cm2-thick target of 9Be.…”

The elastic resonance scattering protons decayed from 11B to the ground state of l0Be were measured by using the thick-target technique in inverse kinematics at the Heavy Ion Research Facility in Lanzhou (HIRFL). The obtained excitation functions were well described by a multichannel R-matrix procedure under the kinematics process assumption of resonant elastic scattering. The excitation energy of the resonant states ranges from 13.0 to 17.0 MeV, and their resonant parameters such as the resonant energy £ ,, the spin-parity J n, and the proton-decay partial width I",, were determined from R-matrix fits to the data. Two of these states around E x = 14.55 MeV [7 T = (3/2+ ,5/2+), T,, = 475 ± 80 keV] and Ex = 14.74 MeV [J" = 3 /2 ', Ep = 830 ± 145 keV], and a probably populated state at E, = 16.18 MeV [ V = ( 1 /2 ',3 /2 ') , Vp < 60 keV], are respectively assigned to the well-known states in 11B at 14.34, 15.29, and 16.43 MeV. The isospin of these three states were previously determined to be T = 3/2, but discrepancies exist in widths and energies due to the current counting statistics and energy resolution. We have compared these states with previous measurements, and the observation of the possibly populated resonance is discussed.

Abstract. We present nuclear mass table in the framework of relativistic continuum Hartree-Bogoliubov (RCHB) theory which properly treats pairing correlations in the presence of the continuum. We study the nuclear mass table mainly with spherical symmetry using the density functional PC-PK1. We then briefly discuss on-going calculations for deformed nuclei with axial symmetry in the framework of deformed RCHB theory.

“…One such technique is the storage-ring mass spectrometry [16]. In this work we present the results of the mass measurements performed on short-lived nuclei at the recently commissioned Cooler Storage Ring at the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) [17] and discuss their impact on nuclear structure and nuclear astrophysics.…”

Recent commissioning of the Cooler Storage Ring at the Heavy Ion Research Facility in Lanzhou enabled us to conduct high-precision mass measurements at the Institute of Modern Physics in Lanzhou (IMP). In the past few years, mass measurements were performed using the CSRe-based isochronous mass spectrometry employing the fragmentation of the energetic beams of 58 Ni, 78 Kr, 86 Kr, and 112 Sn projectiles. Masses of short-lived nuclides of on both sides of the stability valley were addressed. Relative mass precision of down to 10 −6 − 10 −7 is routinely achieved. The mass values were used as an input for dedicated nuclear structure and astrophysics studies, providing for instance new insights into the rp-process of nucleosynthesis in X-ray bursts. In this contribution, we briefly review the so far conducted experiments and the main achieved results, as well as outline the plans for future experiments.
