Probing α-clustering in 9Be via complete fusion and elastic scattering measurements. Physics Letters B, 864, 139441. https://doi.org/10.1016/j.physletb.2025.139441.0370-26931873-2445https://hdl.handle.net/11441/175117The intrinsic structure of the 9Be nucleus has been probed by virtue of its influence on reaction dynamics in the 9Be+110Pd collision. Extensive measurements of the complete fusion excitation function have been undertaken across the Coulomb barrier, in conjunction with the measurement of the elastic scattering angular distribution at a few overlapping incident energies. A unified treatment of both processes is carried out by employing 3-body and 4-body Continuum Discretized Coupled Channels calculations, which exclusively cater to the dynamical features of the collision contingent on the low threshold for dissociation of 9Be into either two or three clusters. A synergy between the complete fusion and elastic scattering measurements across different incident energies is attained when the pivotal description of 9Be as α+α+n configuration is invoked. While the elastic scattering angular distribution is observed to be sensitive to the continuum couplings, the fusion excitation function is primarily influenced by the structure of 9Be in its ground state. The α+α+n picture further reveals an absence of above-barrier fusion suppression when compared with the Universal Fusion Function, in contrast to the commonly reported signature for reactions induced by the 9Be projectile.application/pdf6 p.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Complete fusion excitation functionElastic scattering angular distributionCDCC calculationsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1016/j.physletb.2025.139441
