“…Overall, the non-resonant data from the two different methods are in good agreement; while the present data essentially agree with the Imhof data above the 254-keV resonance (within less than 10%), at energies below the resonance they are systematically about 20-25% lower than the previous data, although still within the 15-20% uncertainties of the individual data points. At energies above ∼200 keV the data deviate from the expected inverse velocity (1/v) dependence for s-wave capture (red solid line) which has been well established at lower energies [14] as will be discussed in the next section.…”

“…In order to describe the data at higher energy a higher-order polynomial description might be necessary. The value for s 0 from the unconstrained fit can be compared to the slope extracted from the direct measurement of σ n,γ for energies between ∼1 eV and ∼1 keV by Blackmon et al [14]. After transforming to the laboratory system and correcting for the excited state contribution it translates to a slope of 6.…”

“…The neutron capture reaction on 7 Li can be directly measured so that the validity of the Coulomb dissociation method to deduce the capture cross section of the inverse reaction can be tested. Indeed, the excitation function of the reaction 7 Li(n,γ) 8 Li has been measured over a wide range of energies from a few meV up to 1 MeV [11][12][13][14][15][16] 8 Li projectile to an excitation energy E x above the neutron separation energy S n of 2.032 MeV, 8 Li decays to 7 Li with a decay energy of E d = E x − S n . In the direct process, a neutron is captured with energy E d and a γ-ray of energy E x is emitted.…”

The applicability of Coulomb dissociation reactions to determine the cross section for the inverse neutron capture reaction was explored using the reaction 8 Li(γ,n) 7 Li. A 69.5 MeV/nucleon 8 Li beam was incident on a Pb target, and the outgoing neutron and 7 Li nucleus were measured in coincidence. The deduced (n,γ) excitation function is consistent with data for the direct capture reaction 7 Li(n,γ) 8 Li and with low-energy effective field theory calculations.

Background: Detailed experimental knowledge of the level structure of light weakly bound nuclei is necessary to guide the development of new theoretical approaches that combine nuclear structure with reaction dynamics.Purpose: The resonant structure of 8 B is studied in this work.Method: Excitation functions for elastic and inelastic 7 Be+p scattering were measured using a 7 Be rare isotope beam. Excitation energies ranging between 1.6 and 3.4 MeV were investigated.An R-matrix analysis of the excitation functions was performed. Conclusions: Identification of the 0 + , 2 + , 1 + states that were predicted by some models at relatively low energy but never observed experimentally is an important step toward understanding the structure of 8 B. Their identification was aided by having both elastic and inelastic scattering data. Direct comparison of the cross sections and phase shifts predicted by the TDCSM and ab initio No Core Shell Model coupled with the resonating group method is of particular interest and provides a good test for these theoretical approaches.

Abstract. The versions of intercluster interaction potentials describing the resonance nature of some phase shifts of the n 7 Li elastic scattering at low energies and the P 2 ground state of 8 Li in the n 7 Li cluster channel have been constructed. The possibility of describing the total cross sections of 7 Li(n, ) 8 Li within the energies from 5 meV (510 -3 eV) to 1 MeV, including resonance at 0.25 MeV, has been demonstrated for the potentials obtained in the potential cluster model with forbidden states.
