We develop a semi-microscopic model to describe transfer reactions. For the sake of simplicity, we focus on nucleon-transfer reactions, but the theory can be generalized to other transfer processes. The model makes use of overlap integrals computed in the microscopic Resonating Group Method (RGM). This technique is based on an effective nucleon-nucleon interaction and on the cluster approximation. It avoids the choice of a nucleon-core potential for the residual nucleus, and does not require any fit of spectroscopic factors. The model is therefore free of parameter. For the entrance channel, we use the Continuum Discretized Coupled Channel (CDCC) method where the breakup of the projectile is simulated by approximations of the continuum. This technique is well known for elastic scattering and for breakup reactions. It is well adapted to weakly bound nuclei such as the deuteron. The model is applied to the 14 C(d, p) 15 C and 6 He(d, n) 7 Li reactions with RGM wave functions of 15 C and of 7 Li. The 15 C nucleus is described by 14 C(0 + , 2 + ) + n configurations whereas 7 Li contains the α + t, 6 He(0 + ) + p and 6 Li(1 + , 0 + ) + n configurations. The spectroscopic factors are in fair agreement with the literature. We show that the model provides an excellent description of the transfer cross sections considering that no parameter is adjusted.

“…Besides the photonuclear reactions, the incident γ beam can also induce Compton effect and pair production in the target, which may influence the detection of the energies of the emitted charged particles. In the present study, Compton effect and pair production are taken into account by invoking the electromagnetic physical process in GEANT4 simulation, and it is indicated that the rate of such background events can be removed by introducing a negligible threshold on the detector [41,99].…”

“…On the experimental side, new accelerator laboratories deep underground (CASPAR in the US [100], LUNA-MV in Italy [9,16,101,102], and JUNA in China [103]) and novel approaches in above-ground facilities have greatly increased the sensitivity of direct reaction-rate measurements. The latter include the use of recoil separators such as ERNA at INFN/Naples [104], St. George at the University of Notre Dame [105], and DRAGON at TRIUMF [106,107]; as well as new detector technologies such as the use of high-resolution silicon detector arrays [108] or active targets that track individual reaction products at TUNL's HIγS [109], quasi-spectroscopic neutron detectors [110],…”

Nuclear Astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the chemical elements. This white paper summarizes progress and status of the field, the new open questions that have emerged, and the tremendous scientific opportunities that have opened up with major advances in capabilities across an ever growing number of disciplines and subfields that need to be integrated. We take a holistic view of the field discussing the unique challenges and opportunities in nuclear astrophysics in regards to science, diversity, education, and the interdisciplinarity and breadth of the field. Clearly nuclear astrophysics is a dynamic field with a bright future that is entering a new era of discovery opportunities.
