Nuclear data evaluation of long-lived fission products: Microscopic vs. phenomenological optical potentials

EPJ Web of Conferences, 2017
Neutron-nucleus cross sections calculated by macroscopic potentials are compared with a microscopic one to study the performance for long-lived fission products. The macroscopic potentials show a good agreement with the microscopic one at higher energies,

Study of (n,2n) reaction cross section of fission product based on neural network and decision tree models [PDF]

EPJ Web of Conferences
The neutron induced nuclear reaction cross sections of fission products are related with the neutron fiux and the reactor burnup, which are important for the accurate of nuclear engineering design. To predict the (n,2n) reaction cross section, especially

Nuclear Data from AMS & Nuclear Data for AMS – some examples [PDF]

EPJ Web of Conferences, 2012
We summarize some recent cross-section measurements using accelerator mass spectrometry (AMS). AMS represents an ultra-sensitive technique for measuring a limited, but steadily increasing number of longer-lived radionuclides. This method implies a two-step procedure with sample activation and subsequent AMS measurement.
