Abstract

To study the conditions leading to the appearance of the threshold anomaly in systems involving weakly bound projectiles we measured elastic scattering cross sections for the {sup 7}Li+{sup 27}Al system at ten different bombarding energies. The results were exhaustively analyzed using different optical model potentials. The similar behavior observed in all these analyses allows us to conclude that no threshold anomaly is found for the present system.

Threshold anomaly with weakly bound projectiles: Elastic scattering of {sup 9}Be+{sup 27}Al

Journal Article Gomes, P; Anjos, R; Muri, C; ... - Physical Review. C, Nuclear Physics

Elastic scattering of the weakly bound {sup 9}Be on {sup 27}Al was measured at near barrier energies. The optical model data analysis with the real and imaginary parts of a global double-folding potential does not show strong evidence of the usual threshold anomaly. The same result was obtained by using a Woods-Saxon shape optical potential and calculating the potential strengths at the strong absorption radius. The reason for this behavior may be explained by the presence of break-up and/or transfer channels at low energies.

Breakup threshold anomaly in the elastic scattering of {sup 6}Li on {sup 27}Al

Journal Article Figueira, J; Niello, J; Abriola, D; ... - Physical Review. C, Nuclear Physics

Elastic scattering of the weakly bound {sup 6}Li on {sup 27}Al was measured at near-barrier energies. The data analysis was performed using a Woods-Saxon shape optical potential and also using the double-folding Sao Paulo potential. The results show the presence of the breakup threshold anomaly (BTA), an anomalous behavior when compared with the scattering of tightly bound nuclei. This behavior is attributed to a repulsive polarization potential produced by the coupling to the continuum breakup states.

Effect of the breakup on the fusion and elastic scattering of weakly bound projectiles on {sup 64}Zn

Journal Article Gomes, P; Padron, I; Anjos, R; ... - Physical Review. C, Nuclear Physics

We study the behavior of the fusion, breakup, reaction, and elastic scattering of different projectiles on {sup 64}Zn, at near and above barrier energies. We present fusion and elastic scattering data with the tightly bound {sup 16}O and the stable weakly bound {sup 6}Li, {sup 7}Li, and {sup 9}Be projectiles. The data are analyzed by coupled channel calculations. The total fusion cross sections for these systems are not affected by the breakup process at energies above the barrier. The elastic (noncapture) breakup cross section is important at energies close to and above the Coulomb barrier and increases the reaction crossmore »« less

Breakup threshold anomaly in the near-barrier elastic scattering of {sup 6}Li+{sup 116,112}Sn

Journal Article Deshmukh, N; Mukherjee, S; Patel, D; ... - Physical Review. C, Nuclear Physics

We have measured the elastic scattering of the weakly bound {sup 6}Li on the {sup 116,112}Sn targets, at energies close to the Coulomb barrier. The energy dependence of the interaction potential has been investigated by two different methods and the presence of the breakup threshold anomaly is observed. We have also derived the total reaction cross sections for the above systems and compared them to those of other systems with halo, weakly bound, and tightly bound projectiles on targets with similar masses. The reaction cross sections are largest for systems with halo nuclei, then the systems with no-halo weakly boundmore »« less

Near-Barrier Elastic Scattering of Weakly Bound Nuclei and the Threshold Anomaly

Journal Article Hussein, M; Chamon, L; Gomes, P - AIP Conference Proceedings

It is pointed out that the usual threshold anomaly, found operative in the energy behavior of the imaginary and real parts of the optical potential representing the elastic scattering of tightly bound nuclei at near- and below-barrier energies, suffers a drastic qualitative change in the case of the elastic scattering of weakly bound projectile nuclei. Owing to the strong coupling to the breakup channel even at sub-barrier energies, the imaginary potential strength seems to increase as the energy is lowered down to below the natural, barrier, threshold, accompanied by a decrease in the real potential strength. This feature is consistentmore »« less
