Core Theoretical Model: The Liquid Drop Model
The Liquid Drop Model (LDM) serves as a classical framework for understanding the macroscopic properties of atomic nuclei. It describes binding energy through volume, surface, Coulomb, symmetry, and pairing terms. This research uses LDM as a baseline, calculating single-nucleon separation energies (Sn, Sp) as the difference in binding energies between parent and daughter nuclei.
AI Enhancement: Artificial Neural Network
Artificial Neural Networks (ANN) are employed to refine LDM predictions. The network utilizes a 2-hidden-layer architecture with 20 neurons each, employing the ReLU activation function and Stochastic Gradient Descent (SGD) for optimization. Key input features include proton (Z) and neutron (N) numbers, and their absolute differences from magic numbers (|Z-Z₀|, |N-N₀|), enabling the ANN to learn complex residuals.
Targeted Optimization: Partitioning Schemes
To address varied nuclear characteristics, three partitioning schemes were applied during ANN training: 1) Proton Magic-Number Partitioning (based on Z ranges like 8≤Z<20, 20≤Z<50, etc.), 2) Neutron Magic-Number Partitioning (based on N ranges), and 3) Z/N Parity Partitioning (categorizing nuclei by even/odd Z and N). These strategies enable the ANN to provide more accurate local optimizations.

Strategic Implications for Nuclear Research and Energy
The enhanced precision in predicting single-nucleon separation energies directly supports major scientific challenges. Understanding nucleosynthesis mechanisms, crucial for the origin of elements, relies on accurate nuclear data. Predicting superheavy nuclei stability and the "island of stability" becomes more reliable. Furthermore, the refined models contribute to innovations in nuclear energy technologies, offering a robust theoretical foundation for future developments.
