“…Application of the ANC theory [19][20][21][22][23] to peripheral reactions on light nuclei is especially adequate for determining the radii of halos [17,24]. In actual practice, the ANC theory is widely used to obtain spectroscopic and astrophysical information [25][26][27][28][29].…”

“…However, the DWBA method does not treat the three body problem exactly. This can be done with the CDCC (Continuum Discretized Coupled Channel) [40] and ADWA (Adiabatic Wave Approximation) [41,42] method, which treats the breakup effect of the deuteron effectively by simply replacing the deuteron-target potential with the proton-and neutron-target potential evaluated at the half incident energies. For the purpose of current study, we consider using…”

In the T-matrix form of transfer reaction, the optical model potentials (OMPs) are used to compute the scattering wave function and transition operator. For most cases, the elastic scattering cross sections, normally used to generate the OMPs, are not directly given in the same experiment. Then the global OMPs, which fit the experimental data over a broad mass and energy range, have been widely used in the theoretical calculations. Different sets of global OMPs with different parameter sets can reproduce the scattering cross section equally well within the uncertainty. Here, we apply different global OMPs to calculate the (differential) cross sections of (d, p) transfer reactions on target nuclei 12C, 48Ca, 124Sn and 208Pb at different energies. The results demonstrate that the effects of deuteron and nucleon global OMPs on transfer (differential) cross sections vary with energy and the target mass. Furthermore, the influences of the spin-orbit coupling term of deuteron and nucleon global OMPs on the transfer cross sections are not negligible.

“…Single nucleon transfer reactions, such as ( ) and ( ) reactions, have been the primary SF extraction tools over the decades. However, an important issue remains: the SFs extracted from transfer reactions show large uncertainties resulting from experimental measurements [3] and theoretical predictions [4][5][6][7][8]. The latter uncertainty type is typically associated with the choice of reaction models, optical model potentials (OMPs), and single-particle potential (SPP) parameters.…”

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.
