43. Study on the origin of 10B in 6Li+12C reaction at energies around Coulomb barrier

Zetao Zhang

The weakly bound nuclei with relatively low binding energy and a greater breakup possibility, such as 6Li,7Li, 9Be, will result in complex reaction processes, such as CF (complete fusion), ICF (incomplete fusion), NCBU(non-capture breakup) and transfer processes, etc. The transfer reaction includes stripping and pickup processes. From the above processes, the reactions induced by weakly bound...

44. One-neutron stripping processes to excited states of the 6Li+ 94,96Zr reaction at near-barrier energies

Mr Tao Yang (Beihang University)

19/08/2020, 15:45

Direct transfer of neutrons involving stable and radioactive weakly bound projectiles have been investigated in the past few years to contribute to the reaction and scattering mechanisms. At the energy around the Coulomb barrier, the neutron transfer reaction may cause the fission reaction and the enhancement of fusion cross sections to some systems, and the influence of neutron transfer on...

36. Study of the fusion reaction of 6Li + 94,96Zr systems at near-barrier energies

Ms Su Xuedou (Beihang University)

19/08/2020, 16:00

Investigation of fusion reaction induced by weakly bound nuclei is one of important topics in recent years. Because weakly bound nuclei break up before entering the fusion barrier, the incident flux of the complete fusion reaction channel is reduced. Therefore, the complete fusion cross section occurs suppression phenomenon. In order to study the suppression factor of complete fusion cross...

46. Study of complete-incomplete fusion mechanisms in ${}^7$Li+${}^{89}$Y reaction.

Mr Rinku Prajapat (Department of Physics, Indian Institute of Technology Roorkee, Roorkee-247667, Uttarakhand, India)

19/08/2020, 16:20

Fusion mechanism of weakly bound stable (${}^{6,7}$Li and ${}^9$Be) and unstable halo (${}^{11}$Li, ${}^{7,11}$Be, and ${}^8$B) nuclei is a subject of great interest from the past few years [1,2]. Due to their low breakup threshold, various reaction processes like complete-incomplete fusion (CF-ICF), elastic breakup, and transfer followed by a breakup, appear in the reaction dynamics. Hence, to...

48. Does positive Q-value neutron transfer channels influence sub-barrier fusion?

Rudra N. Sahoo (Indian Institute of Technology Ropar, India)

19/08/2020, 16:35

In heavy-ion induced reactions, sub-barrier fusion plays a crucial role in studying the static and dynamic properties of the nucleus and understanding the astrophysical processes in the steller environment [1]. However, the sub-barrier mechanism is not yet fully explored due to insufficient systematic studies and experimental measurements [2,3]. To unravel the role of positive Q-value neutron...

52. Probing for the systematic behavior of incomplete fusion fraction and complete fusion suppression induced by 12,13C on 165Ho target

Dr Suhail A. Tali (Department of Physics, Aligarh Muslim University, Aligarh –202002, India)

Abstract

Fusion reactions induced by Heavy Ions play a role of paramount importance in nuclear physics, as they help the nuclear physicists to study the properties of superheavy nuclei near and away from the stability line. In the reactions involving heavy ion projectiles such as 12C, 13C, 16O, 18O etc., and heavier mass targets at projectile energies below 8 MeV/nucleon, the two most...

7. Unbound states in ${}^{16,18,20}$C with the R${}^3$B setup: the search for the mixed-symmetry 2${}^{+}$ state

Silvia Murillo Morales (University of York)

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 mechanism behind the shell evolution.
Recently, ${}^{\mathrm{A}}\mathrm{N}$(p,2p)${}^{\mathrm{A}-1}\mathrm{C}$ quasi-free scattering reactions were...

45. Coulomb and Nuclear breakup of 6He

Atsumi Saito, Prof. Takashi Nakamura (Tokyo Institute of Technology)

19/08/2020, 17:25

We performed exclusive measurements of breakup reactions of 6He into 4He+2n on CH2, C, Sn, and Pb targets at 184 MeV/nucleon using the SAMURAI setup at the RI-beam factory (RIBF).
The highest-statistics experiments in these reactions owing to the combination of NeuLAND and NEBULA neutron detector arrays [1, 2] allowed us to study in detail these breakup reactions, the low-lying excited...

31. Experimental study of ${}^4$n with ${}^8$He(p,2p) reaction

Mr SIWEI HUANG (Peking University, China & Nishina Center/RIKEN, Japan)

19/08/2020, 17:40

The tetraneutron(${}^4$n), has attracted a lot of attention in the last decades. Its existence, whether as bound or resonant states, is of fundamental importance in nuclear physics, serving as a sensitive probe to investigate the nuclear force free from the Coulomb interaction. In case the four constituent neutrons are detected, it will also provide direct information about many-neutron...
