Using the advanced GALILEO matrix coupled to the 4π Si-ball EUCLIDES, the researchers performed a thorough spectroscopic analysis to track and identify the reactions. The gamma-gamma matching method was crucial to isolating specific reaction channels, allowing the team to determine the behavior of nuclei under different conditions with high precision.

Researchers have made significant progress in understanding neutron transport in weakly bound nuclei. The experiment, carried out at the Legnaro National Laboratory, focused on the process of releasing a single neutron in reactions involving lithium-6 and bismuth-209. The work was published in Nuclear Sciences and Techniques.
Joint research efforts have shown that the single-neutron separation process produces results comparable to those of full fusion reactions, especially in energy regions near nuclear barriers. Contrary to previous expectations, the results show that single-neutron transfer plays a dominant role at lower energies, exceeding the yield of fusion reactions.
This research builds on decades of research into how loosely bound nuclei like lithium-6 interact with heavier nuclei. Lithium-6 is known for its delicate structure, which makes it susceptible to decay and involvement in complex reaction pathways. The study confirmed that even as the energy decreases, the impact of these reactions remains significant, providing new insights into how nuclear interactions occur under different conditions.

Improved nuclear application strategies
“By better understanding the behavior of nuclei under these conditions, we can improve our approaches to nuclear power generation and radiotherapy,” said J. Lubian, the study’s corresponding author. This research paves the way for potential applications in medical physics and energy research, where accurate knowledge of nuclear processes is critical.
The process of shedding a single neutron highlights the complex and nuanced nature of nuclear reactions, providing a stepping stone for future scientific breakthroughs in nuclear science and technology.
