Title: Fusion of neutron-rich oxygen nuclei

Abstract

Measurement of the fusion excitation function for ¹⁸O + ¹²C and ¹⁹O + ¹²C is described. The fusion cross-section is extracted through the direct measurement of evaporation residues resulting from the fusion process. At near barrier energies, the single additional neutron present in ¹⁹O results in an enhancement in the fusion cross-section by a factor of over three as compared to ¹⁸O.

Fusion enhancement at near and sub-barrier energies in ¹⁹O + ¹²C

Journal Article Singh, Varinderjit ; Vadas, J. ; Steinbach, T. K. ; ... - Physics Letters. Section B

Measuring the fusion excitation function for an isotopic chain of projectile nuclei provides a stringent test of a microscopic description of fusion. We report the first measurement of the fusion excitation function at near-barrier energies for the ¹⁹O+ ¹²C system. The measured excitation function is compared with the fusion excitation function of ¹⁸O+ ¹²C. A significant enhancement in the fusion probability of ¹⁹O ions with a ¹²C target as compared to ¹⁸O ions is observed. As a result, the experimental cross-sections observed at near-barrier energies are compared with a state-of-the-art microscopic model.

Probing the fusion of neutron-rich nuclei with re-accelerated radioactive beams

Journal Article Vadas, J. ; Singh, Varinderjit ; Wiggins, B. B. ; ... - Physical Review C

Here, we report the first measurement of the fusion excitation functions for ^39,47K + ²⁸Si at near-barrier energies. Evaporation residues resulting from the fusion process were identified by direct measurement of their energy and time-of-flight with high geometric efficiency. At the lowest incident energy, the cross section measured for the neutron-rich ⁴⁷K-induced reaction is ≈6 times larger than that of the β-stable system. This experimental approach, both in measurement and in analysis, demonstrates how to efficiently measure fusion with low-intensity re-accelerated radioactive beams, establishing the framework for future studies.

Comparison of /sup 6/Li- and /sup 7/Li-induced fusion cross sections on /sup 16/O

Journal Article Mateja, J.F. ; Frawley, A.D. ; Dennis, L.C. ; ... - Phys. Rev. C; (United States)

The heavy residues emitted following the interaction of /sup 6/Li and /sup 16/O have been measured for /sup 6/Li bombarding energies from 12 to 35 MeV. The gross characteristics of the residue spectra are in qualitative agreement with a fusion-evaporation mechanism. Beginning at Coulomb barrier energies, it is found that the total fusion cross section diverges from the total reaction cross section obtained from optical model fits to /sup 6/Li+ /sup 16/O elastic scattering data. The importance of the process which limits the /sup 6/Li+ /sup 16/O fusion cross section is attested to by the fact that only 60% ofmore »« less

Studying neutron-rich 18 N in fusion-evaporation reactions

Technical Report Wiedeking, M ; Fallon, P ; Bernstein, L ; ...

Light neutron-rich nuclei provide an excellent opportunity to study the changes in nuclear shell structure that occur with increasing neutron number and are an important testing ground for shell model theories. Probably one of the most striking examples of shell modification is the occurrence of intruder ground states, which signal an inversion of the normal shell ordering. Intruder ground states are observed around {sup 32}Mg (Z=10-12), ''the island of inversion'', and in {sup 11}Be. An analogous situation appears in the Z=2 He isotopes, where the intrusion of sd excitations in p-shell configurations becomes important in the heavy helium isotopes. Finally,more »« less
