In the heart of the Kurdistan Region, Iraq, a physicist is unraveling the mysteries of nuclear fusion, with implications that could echo through the energy sector. Lina S. Abdalmajid, from the University of Halabja, has been delving into the intricate dance of atomic nuclei, specifically how oxygen isotopes can enhance sub-barrier fusion—a process that could potentially revolutionize energy production.
Abdalmajid’s research, published in the Iraqi Journal of Physics, explores how the deformation of projectiles and the dynamics of coupled channels, including neutron transfer and multipole vibrations, influence fusion cross-sections. In simpler terms, she’s investigating how different types of oxygen atoms can merge with other nuclei more efficiently, even at lower energies where fusion typically doesn’t occur.
The study uses advanced theoretical models, including Wong’s formula and a modified version of the CCFULL code, to calculate fusion excitation functions and barrier distributions for various systems. The results are promising, with the BW91 potential showing significant improvement in predicting experimental data when inelastic excitations and neutron transfer reactions are included.
“Barrier distribution analysis shows the crucial role of nuclear structure in determining the fusion probability landscape,” Abdalmajid explains. This understanding could pave the way for more efficient fusion reactions, a holy grail in the quest for clean, limitless energy.
The research highlights the enhanced fusion cross-sections for systems involving oxygen-18, particularly with tin-116 and lead-208 targets. The calculated cross-section value for the oxygen-18 and tin-116 system was double that of the oxygen-16 and tin-116 system, indicating a significant enhancement in fusion probability.
The implications for the energy sector are profound. If we can better understand and control these sub-barrier fusion processes, we could potentially develop more efficient and sustainable energy sources. “This research serves as a benchmarking technique for assessing theoretical calculations,” Abdalmajid notes, underscoring its importance in advancing our understanding of nuclear fusion.
As we stand on the brink of a potential energy revolution, Abdalmajid’s work offers a glimpse into the future. By unraveling the complexities of nuclear fusion, she is not only contributing to scientific knowledge but also shaping the trajectory of the energy sector. Her research, published in the Iraqi Journal of Physics, is a testament to the power of curiosity and the potential of nuclear physics to transform our world.
