“…Within this approach, interesting results were found for the 18 O-induced one-and two-neutron transfer reactions. For a long time, the approximations used to deal with the complex many-body aspects of the reactions led to the use of arbitrary scaling factors in the calculated cross sections in order to compare them with the experimental results [22,23], preventing the extraction of accurate nuclear structure information. With the advent of microscopic approaches based on DWBA and coupled-channels (CC) schemes with double-folding potentials and spectroscopic amplitudes derived from large-scale shell model (SM) or interacting boson model (IBM) [24], it was possible to give a satisfactory description of the measured cross sections [25][26][27][28][29][30][31].…”

Background: Heavy-ion induced two-nucleon transfer reactions are powerful tools to reveal peculiar aspects of the atomic nucleus, such as pairing correlations, single-particle and collective degrees of freedom, and more. Also, these processes are in competition with the direct meson exchange in the double charge exchange reactions, which have recently attracted great interest due to their possible connection to neutrinoless double-β decay. In this framework, the exploration of two-nucleon transfer reactions in the 20 Ne + 116 Cd collision at energies above the Coulomb barrier is particularly relevant since the 116 Cd nucleus is a candidate for the double-β decay.Purpose: We want to analyze selected transitions to low-lying 0 + and 2 + states of the residual nuclei in the 116 Cd( 20 Ne, 22 Ne) 114 Cd two-neutron pickup and 116 Cd( 20 Ne, 18 O) 118 Sn two-proton stripping reactions at 306 MeV incident energy and determine the role of the couplings with inelastic transitions. Methods: We measured the excitation energy spectra and absolute cross sections for the two reactions using the MAGNEX large acceptance magnetic spectrometer to detect the ejectiles. We performed direct coupled reaction channels and sequential distorted wave Born approximation calculations using the double folding São Paulo potential to model the initial and final state interactions. The spectroscopic amplitudes for two-and singleparticle transitions were derived by different nuclear structure approaches: microscopic large-scale shell model, interacting boson model-2 and quasiparticle random phase approximation. Results:The calculations are able to reproduce the experimental cross sections for both two-neutron and twoproton transfer reactions. The role of couplings with the inelastic channels are found to be important in the two-proton transfer case. A competition between the direct and the sequential process is found in the reaction *

The energies of the g 7/2 and h 11/2 neutron orbitals in N = 51 isotones have been investigated. The single-neutron adding reactions (d,p) and (α, 3 He) have been performed on 88 Sr, 90 Zr and 92 Mo targets, at beam energies of 15 MeV and 50 MeV, respectively. These measurements were supplemented by studying the d(86 Kr,p) 87 Kr reaction at an energy of 10 MeV/u, in inverse kinematics. Absolute cross sections were measured, assignments made and spectroscopic factors extracted. The energy centroids of the single-particle strength have been deduced and the observed trends are discussed.

“…Bound-state parameters for a neutron in the α-particle projectile (r = 1.20 fm and a = 0.65 fm) were taken from Ref. [33]; those for a neutron bound to the target (r = 1.25 fm, a = 0.63 fm, V so = 7 MeV, r so = 1.10 fm and a so = 0.50 fm) were from Ref. [34].…”

The single-neutron properties of N = 51 nuclei have been studied with the (d,p) and (α, 3 He) reactions, at beam energies of 15 and 50 MeV respectively, on 88 Sr, 90 Zr, and 92 Mo targets. The light reaction products were momentum analyzed using a conventional magnetic spectrometer. Additionally, the 2 H(86 Kr,p) reaction was measured at a beam energy of 10 MeV/u, where outgoing light ions were analyzed using a helical-orbit spectrometer. Absolute cross sections and angular distributions corresponding to the population of different final states in the heavy product were obtained for each reaction. Spectroscopic factors were extracted and centroids of the single-particle strength were deduced. The observations appear consistent with calculations based on an evolution of single-particle structure driven by the nucleon-nucleon forces acting between valence protons and neutrons.
