(d, 3n) Reaction cross-section calculation of some reactor materials

Area of Science:

• Nuclear Physics
• Materials Science

Background:

• Charged particle nuclear reactions are vital for radioisotope production, astrophysics, and understanding nuclear reaction mechanisms.
• Studying these reactions is crucial for assessing radiation damage effects on fusion reactor structural materials.

Purpose of the Study:

• To theoretically calculate cross-section data for specific deuteron-induced reactions.
• To evaluate the accuracy of nuclear reaction codes and empirical formulas against experimental data.

Main Methods:

• Theoretical cross-section calculations using ALICE/ASH, TALYS 1.95, and Empire 3.2.2 codes for reactions like 45Sc(d, 3n)44Ti.
• Optical Model Parameters (OMP) for deuteron-induced reactions calculated via TALYS 1.95.
• Comparison of theoretical results with an empirical (d, 3n) cross-section formula and experimental EXFOR data.

Main Results:

• Cross-section data were calculated for 45Sc (d, 3n)44Ti, 63Cu (d, 3n)62Zn, 89Y (d, 3n)88Zr, and 100Mo (d, 3n)99Tc reactions (1-50 MeV).
• TALYS 1.95 code accurately reproduced deuteron-induced reaction cross-section values.
• Theoretical calculations showed compatibility with empirical formulas and experimental EXFOR data.

Conclusions:

• The study validates the use of nuclear reaction codes for predicting cross-sections relevant to fusion energy applications.
• Theoretical calculations provide reliable data for understanding and mitigating radiation damage in fusion reactor materials.
