Disentangling single-particle and collective signatures in 12C(p,2p)11B reaction

E. Cravo, Raquel Crespo, Arnoldas Deltuva, D. Jurčiukonis

We calculate kinematically fully exclusive cross sections for the 12C(p,2p)11B reaction at Ep=98.7 MeV proton beam energy, leading to the low-lying states of 11B. We use rigorous three-particle scattering framework extended to include simultaneously and consistently both core excitation and single-particle-like excitations. …

Quenching of the quantum p-strength in light exotic nuclei

E. Cravo, Robert B. Wiringa, Raquel Crespo, A. Arriaga et autres

One-nucleon spectroscopic overlaps, their strength or spectroscopic factors (SFs), and nucleon removal cross sections for light nuclei in the mass range A≤12 were evaluated using the fully correlated Quantum Monte Carlo (QMC) wave functions (WFs). Harder (AV18+UX) and softer (NV2+3) bare interactions …

Interplay of single-particle and collective modes in the 12C(p,2p) reaction near 100 MeV

Arnoldas Deltuva, E. Cravo, Raquel Crespo, D. Jurčiukonis

The 12 C(p,2p) 11 B reaction at E p =98.7 MeV proton beam energy is analyzed using a rigorous three-particle scattering formalism extended to include the internal excitation of the nuclear core or residual nucleus. The excitation proceeds via the core interaction …

Interplay of single-particle and collective modes in the $^{12}$C(p,2p) reaction near 100 MeV

Arnoldas Deltuva, E. Cravo, Raquel Crespo, D. Jurčiukonis

The $^{12}$C(p,2p)$^{11}$B reaction at $E_p =98.7$ MeV proton beam energy is analyzed using a rigorous three-particle scattering formalism extended to include the internal excitation of the nuclear core or residual nucleus. The excitation proceeds via the core interaction with any of the …

A new Time-of-flight detector for the R$$^3$$B setup

M. Heil, A. Kelić-Heil, Tahani Almusidi, Hector Alvarez-Pol et autres

Abstract We present the design, prototype developments and test results of the new time-of-flight detector (ToFD) which is part of the R $$^3$$ 3 B experimental setup at GSI and FAIR, Darmstadt, Germany. The ToFD detector is able to detect heavy-ion residues …

Isotopic cross sections of fragmentation residues produced by light projectiles on carbon near 400 A MeV

J. M. Boillos, Dolores Cortina-Gil, J. Benlliure, Jose Luis Rodriguez-Sanchez et autres

We measured 135 cross sections of residual nuclei produced in fragmentation reactions of $^{12}\mathrm{C}, ^{14}\mathrm{N}$, and $^{13\ensuremath{-}16,20,22}\mathrm{O}$ projectiles impinging on a carbon target at kinetic energies of near $400A$ MeV, most of them for the first time, with the $\mathrm{R}^{3}\mathrm{B}$/LAND setup at …

Probing the Z = 6 spin-orbit shell gap with (p,2p) quasi-free scattering reactions

I. Syndikus, Marina Petri, Augusto O. Macchiavelli, S. Paschalis et autres

The evolution of the traditional nuclear magic numbers away from the valley of stability is an active field of research. Experimental efforts focus on providing key spectroscopic information that will shed light into the structure of exotic nuclei and understanding the driving …

Many-body effects in (p,pN) reactions within a unified approach

Raquel Crespo, A. Arriaga, Robert B. Wiringa, E. Cravo et autres

We study knockout reactions with proton probes within a theoretical framework where ab initio Quantum Monte Carlo (QMC) wave functions are combined with the Faddeev/Alt-Grassberger-Sandhas few-body reaction formalism. QMC wave functions are used to describe 12C, yielding, for the first time, results …

Interplay of dynamical and structure effects in the observables for 12C(p,2p) near 400 MeV with polarized and unpolarized beams

Angela Mecca, E. Cravo, Arnoldas Deltuva, Raquel Crespo et autres

We investigate the interplay of reaction mechanism and structure effects in the calculated cross sections and polarization observables for the direct C12(p,2p) reaction near 400 MeV around the Quasi Free Scattering (QFS) kinematical condition. We do the first consistent comparison between the …

Quasi-free neutron and proton knockout reactions from light nuclei in a wide neutron-to-proton asymmetry range

Matthias Holl, V. Panin, Hector Alvarez-Pol, L. Atar et autres

The quasi-free scattering reactions 11 C ( p , 2 p ) and 10,11,12 C ( p , p n ) have been studied in inverse kinematics at beam energies of 300–400 MeV/u at the R 3 B-LAND setup. The outgoing proton-proton …

Three-body calculations for (p,pN) reactions: Kinematically inclusive, semi-inclusive, and fully exclusive cross sections

Raquel Crespo, E. Cravo, Arnoldas Deltuva

Background: Nucleon knockout reactions have been previously used to extract single particle information from nuclei. The analysis of nucleon knockout from a stable projectile in the collision with a proton target and the comparison with the experimental data is a key test …

Structure of Be 13 studied in proton knockout from B 14

Geraldo Monteiro Ribeiro, Enrique Nácher, O. Tengblad, P. Díaz Fernández et autres

The neutron-unbound isotope $^{13}\mathrm{Be}$ has been studied in several experiments using different reactions, different projectile energies, and different experimental setups. There is, however, no real consensus in the interpretation of the data, in particular concerning the structure of the low-lying excited states. …
