“…In Ref. [66], the discrepancy between the ADWA and Faddeev models was found to be much larger at 50 MeV/nucleon than at 28 MeV/nucleon in the 48 Ca( ) 49 Ca case, resulting in larger SFs at higher energies, consistent with our present findings. A systematic analysis by solving the Faddeev-AGS equations would be interesting and may help to further understand the systematic discrepancy.…”

The consistent three-body model reaction methodology(TBMRM) proposed by J. Lee et al.[1–3], which includes adopting the simple zero-range adiabatic wave approximation, constraining the single-particle potentials using modern Hartree–Fock calculations, and using global nucleon optical model potential(OMP) geometries, are widely applied in systematic studies of transfer reactions. In this work, we study the influences of different nucleon OMPs on extraction of spectroscopic factors(SFs) from (p, d) reactions. Our study covers 32 sets of angular distribution data of (p, d) reactions on 4 targets, as well as a large range of incident energies(20-200 MeV/nucleon). Two semi-microscopic nucleon OMPs, JLM[4, 5] and CTOM[6], and a pure microscopic nucleon potential WLH[7] are used in the present work. The results are compared with those using the phenomenological global optical potential KD02[8]. We find the incident energy dependence of spectroscopic factors extracted from (p, d) reactions is obviously suppressed when microscopic OMPs are employed for 12C, 28Si and 40Ca. In addition, spectroscopic factors extracted using the systematic microscopic optical potential CTOM based on the Dirac-Brueckner-Hartree-Fock theory are more in line with the results obtained from (e, e'p) measurements, except 16O and 40Ca at high energies(> 100 MeV), calling for an exact treatment of double-magic nuclei. The results obtained by using pure microscopic optical potential WLH based on EFT theory shows the same trend but generally higher than CTOM. JLM potential, which relies on simplified nuclear matter calculations with old-fashioned bare interactions, produces very similar results with phenomenological potential KD02. Our results indicate that modern microscopic OMPs are reliable tools for probing the nuclear structure by transfer reactions across a wide energy range.

Erratum: Lattice study of the two-photon decay widths for scalar and pseudo-scalar charmonium [Chin. Phys. C 44(8), 083108 (2020)]

Abstract: We have corrected the decay width for the two photon decay widths for scalar and pseudo-scalar Charmonium in [Chinese Physics C Vol.44,No.8(2020)083108]. The decay widths are now in better agreement with the experiment values.
