“…5(a) and 5(b), respectively, we compare the 2 H(α, d) 4 He deuteron elastic recoil and 4 He(d, d) 4 He deuteron elastic scattering differential cross sections computed using the N N +3N Hamiltonian to the measured energy distributions of Refs. [7][8][9][42][43][44][45]. Aside from the position of the 3 + resonance, the calculations are in fair agreement with experiment, particularly in the low-energy region of interest for the Big-bang nucleosynthesis of 6 Li, where we reproduce the data of Besenbacher et al [42] and those of Quillet et al [8].…”

“…C0 C2 C2/C0 He center-of-mass frame angular differential cross sections (lines) using the N N +3N Hamiltonian at the deuteron recoil and backscattered angles of, respectively, ϕ d = 30 • and θ d = 164 • as a function of the laboratory helium (Eα) and deuteron (E d ) incident energies, compared with data (symbols) from Refs.

In panel (c), calculated (lines) and measured (symbols) center-of-mass angular distributions at E d = 2.93, 6.96, 8.97 [46], and 12 MeV [47] are scaled by a factor of 20, 5, 2, and 1, respectively.…”

Prototype for the study of weakly bound projectiles colliding on stable targets, the scattering of deuterium (d) on 4 He (α) is an important milestone in the search for a fundamental understanding of low-energy reactions. At the same time, it is also important for its role in the Big-bang nucleosynthesis of 6 Li and applications in the characterization of deuterium impurities in materials. We present the first unified ab initio study of the 6 Li ground state and d-4 He elastic scattering using two-and three-nucleon forces derived within the framework of chiral effective field theory. The sixnucleon bound-state and scattering observables are calculated by means of the no-core shell model with continuum. We analyze the influence of the dynamic polarization of the deuterium and of the chiral three-nucleon force, and examine the role of the continuum degrees of freedom in shaping the low-lying spectrum of 6 Li. We find that the adopted Hamiltonian correctly predicts the binding energy of 6 Li, yielding an asymptotic D-to S-state ratio of the 6 Li wave function in d + α configuration of −0.027 in agreement with the value determined from a phase shift analysis of 6 Li+ 4 He elastic scattering, but overestimates the excitation energy of the first 3 + state by 350 keV. The bulk of the computed differential cross section is in good agreement with data.

“…The next state is 17.98 MeV above the ground state. The 3 + state appears as a clear resonance in the 2 H+ 4 He cross section, 2.186 MeV above the ground state (or 0.7117 MeV above the scattering threshold, at E d = 1.067 MeV or E α = 2.135 MeV) [20][21][22][23][24][25][26]. Also evident is the 2 + 1 resonance 4.31 MeV above the 6 Li ground state (or 2.8375 MeV above the scattering threshold, at E d = 4.253 MeV or E α = 8.507 MeV) [21,[27][28][29].…”

An effective two-body model for spectra of clusters of ${}^2$H, ${}^3$H, ${}^3$He, and $^4$He with $^4$He, and $^2$H-$^4$He scattering

Four light-mass nuclei are considered by an effective two-body clusterisation method; 7 Li as 3 H+ 4 He, 7 Be as 3 He+ 4 He, 8 Be as 4 He+ 4 He, and 6 Li as 2 H+ 4 He. The low-energy spectra of the former three are determined from single-channel Lippmann-Schwinger equations. For the latter, two uncoupled sets of equations are considered; those involving the 3 S 1 and those of the posited 1 S 0 states of 2 H. Low-energy elastic scattering cross sections are calculated from the same 2 H+ 4 He Hamiltonian, for many angles and energies for which data are available. While some of these systems may be more fully described by many-body theories, this work establishes that a large amount of data may be explained by these two-body clusterisations.

“…There, the 1 H(α,p) 4 He angular differential cross-section calculated with the NCSMC is compared to data of Refs. [128][129][130][131][132][133] for a set of proton recoil angles (ϕ). The range in energy of the impinging α particle covers the 3 2 − and 1 2 − resonances where the cross section deviates the most from the Rutherford limit (limit of structureless charged particle scattering).…”

The description of nuclei starting from the constituent nucleons and the realistic interactions among them has been a long-standing goal in nuclear physics. In addition to the complex nature of the nuclear forces, with two-, three-and possibly higher many-nucleon components, one faces the quantum-mechanical many-nucleon problem governed by an interplay between bound and continuum states. In recent years, significant progress has been made in ab initio nuclear structure and reaction calculations based on input from QCD-employing Hamiltonians constructed within chiral effective field theory. After a brief overview of the field, we focus on ab initio many-body approaches -built upon the No-Core Shell Model -that are capable of simultaneously describing both bound and scattering nuclear states, and present results for resonances in light nuclei, reactions important for astrophysics and fusion research. In particular, we review recent calculations of resonances in the 6 He halo nucleus, of five-and six-nucleon scattering, and an investigation of the role of chiral threenucleon interactions in the structure of 9 Be. Further, we discuss applications to the 7 Be(p, γ) 8 B radiative capture. Finally, we highlight our efforts to describe transfer reactions including the 3 H(d, n) 4 He fusion.
