Neutron-induced cross section measurements

Neutron-induced cross sections represent the main nuclear input to models of stellar and Big-Bang nucleosynthesis. While (n, gamma) reactions are relevant for the formation of elements heavier than iron, (n,p) and (n,alpha) reactions can play an important role in specific cases. The time-of-flight method is routinely used at n_TOF to experimentally determine the cross section data. In addition, recent upgrades of the facility will allow the use of activation techniques as well, possibly opening the way to a systematic study of neutron interaction with radioactive isotopes. In the last 20 years n_TOF has provided a large amount of experimental data for Nuclear Astrophysics. Our plan is to carry on challenging measurements and produce nuclear data in the next decades as well.

Automated summary

Neutron-induced cross sections are crucial for stellar and Big-Bang nucleosynthesis models. Different reactions, such as (n, gamma), (n, p), and (n, alpha), can play important roles in element formation. The time-of-flight method is commonly used at n_TOF to determine experimental cross section data, and upgrades to the facility will allow for the study of neutron interactions with radioactive isotopes using activation techniques. Over the past 20 years, n_TOF has provided substantial experimental data for Nuclear Astrophysics, and there are plans to continue challenging measurements and generate nuclear data in the future.
