Predictions of complete fusion cross-sections of 6,7Li, 9Be, and 10B using a Bayesian neural network method

This method was trained and validated using 475 experimental data points from 39 reaction systems induced by 6,7Li, 9Be, and 10B. The constructed Bayesian neural network demonstrated a high degree of accuracy in evaluating complete fusion cross-sections.

By comparing thepredicted cross-sections with those obtained from a single-barrier penetration model, the suppression effect of 6,7Li and 9Be with a stable nucleus was systematically analyzed. In the cases of 6Li and 7Li, less suppression was predicted for relatively light mass targets than for heavy mass targets, and a notably distinct dependence relationship was identified, suggesting that the predominant breakup mechanisms might change in different mass target regions.
