Abstract
Calculations of total fusion cross sections of the weakly bound nuclei 6,7 Li with a variety of targets at energies around the Coulomb barrier are presented. Special emphasis is focused on the effects that resonance states, l=2, J π =3 + , 2 + , 1 + of 6 Li, and l=3, J π =7/2 - , 5/2 - of 7 Li, have on fusion. The study uses the Continuum-Discretized Coupled-Channel (CDCC) framework to calculate total fusion, from which the effects of couplings to resonance states are extracted. Resonance states with shorter half-lives have a more important effect on total fusion at energies below and around the Coulomb barrier, where incomplete fusion dominates. On the other side, resonance states with longer half-life, act as quasi-bound inelastic states, thus, these states have a more important role on complete fusion than on incomplete fusion.

期刊介绍:
The journal publishes original, peer-reviewed articles on new and significant advances in all aspects of cell and chromosome research. Timely and substantial articles in the areas of cell biology, genetic toxicology, chromosome evolution, cytogenetics; molecular-, population- and evolutionary genetics; epigenetics; developmental and stress biology; transcriptomics, structural and functional genomics, proteomics, metabolomics, integrated omics and use of tools of bioinformatics in the areas stated herein. Studies demonstrating the use of modern approaches such as genome editing to address technological problems and/or biological questions pertaining to the research areas mentioned above are encouraged. However, the studies should be conducted with appropriate scientific rigor in the design, conduct, validity, and interpretation of results to ensure reliability and reproducibility of the data presented. The papers must be written concisely and be of interest to a broad audience.
The journal also publishes comprehensive reviews on current developments and future trends in cell and chromosome research. Such articles should be authoritative, covering all the aspects of a chosen topic, and serve as a resource for students, researchers, and multidisciplinary audience. Authors are welcome to contact the Editor-in-Chief to discuss their topic of interest while preparing a prospective review article.
Thematic special issues on cutting edge research in the development of the above stated areas are periodically published by the journal. Articles for such issues are commissioned by the respective topic editor/s.
