Nucleus-nucleus potentials in the scattering of tightly and weakly bound systems

Jhony William Maciel Rangel, B. Pinheiro, V. A. B. Zagatto, Jesus Lubian et autres

\begin{description} \item[Background] Fusion reactions play an important role in nucleosynthesis and in applications to society. Yet they remain challenging to model. \item[Purpose] In this work, we investigate the features of the nucleus-nucleus potentials that describe fusion cross sections and compare with those …

One-neutron transfer in C 13 + Sm 144 , 148 at E lab = 56 MeV and 60 MeV

B. R. Gonçalves, Djalma R. Mendes, Roberto Linares, V. A. B. Zagatto et autres

Background: In previous works we have studied the one-neutron transfer reactions induced by $^{13}\mathrm{C}$ on $^{27}\mathrm{Al}$ and $^{28}\mathrm{Si}$ nuclei. Using a multichannel approach, experimental cross sections for elastic, inelastic, and transfer reactions are well described with the same theoretical formalism.Purpose: In this …

Compound nucleus formation effects in heavy-ion fusion cross sections

V. A. B. Zagatto, C.E. Aguiar, Jesus Lubian, L. F. Canto

Heavy-ion-fusion reactions at near-barrier energies take place in two steps. In the first, the system overcomes the potential barrier. In the second, the collision partners merge to form a single body, losing their identities. Most theoretical models ignore the latter, assuming that …

Status of the NUMEN Construction

D. Pierroutsakou, Luis Acosta, N. Added, C. Agodi et autres

The NUMEN (NUclear Matrix Elements for Neutrinoless double beta decay) project at INFN-Laboratori Nazionali del Sud aims to extract quantitative information on the Nuclear Matrix Elements relevant to neutrinoless double beta decay, a key process for determining whether the neutrino is a …

Multichannel experimental and theoretical approach to the C 12 ( O 18 , F 18 ) B 12 single-charge-exchange reaction at 275 MeV. II. Competition between the meson exchange and the sequential transfer in the reaction mechanism

A. Spatafora, F. Cappuzzello, D. Carbone, M. Cavallaro et autres

Background: Single-charge-exchange reactions are among the most appropriate nuclear tools to study the response of nuclear systems to isovector interaction. Nowadays, the availability of powerful experimental setups and advanced nuclear models bring the possibility of the complete study of the reaction mechanisms …

Improved Wong and classical approximations, and reduction of fusion data

Jorge Cantó, V. A. B. Zagatto, Jesus Lubian, R. Donangelo

We present an improved version of the Wong formula for heavy-ion fusion, where the parameters of the parabolic approximation of the Coulomb barrier are replaced by parameters of the $l$-dependent potential at an effective partial wave. A pocket formula for this $l$ …

Investigation of one-neutron transfer in C13+Al27 at Elab=32MeV

B. R. Gonçalves, Djalma R. Mendes, Roberto Linares, V. A. B. Zagatto et autres

The $^{13}\mathrm{C}+^{27}\mathrm{Al}$ reaction (${E}_{\text{lab}}=32$ MeV) has been measured, and the elastic scattering, target excitation, and one-neutron transfer channels have been investigated. A comparison of the data with the results of different theoretical frameworks indicates the necessity of including the effect of the …
