<i>We provide results of the numerical integration of the one-dimensional Time-Dependent Schrödinger Equation (TDSE) of the helium atom in the interaction with a strong electromagnetic field. We compare different theoretical models: (i) Two Active Electrons (TAE), which is the exact 1D description of the He atom, (ii) Idle Electron model (IDL), considering two-electron correlation, and only one electron interacting with the external field, (iii) Single-Active Electron approximation (SAE), and (iv) the exact 1D description of the helium cation (He⁺). <br></i>

本数据集提供了氦原子与强电磁场相互作用场景下，一维含时薛定谔方程（Time-Dependent Schrödinger Equation，TDSE）的数值积分结果。我们针对四类理论模型展开对比分析：(i) 双活性电子模型（Two Active Electrons，TAE）：该模型为氦原子的精确一维描述；(ii) 惰性电子模型（Idle Electron model，IDL）：该模型考虑双电子关联效应，仅单个电子与外场发生相互作用；(iii) 单活性电子近似（Single-Active Electron approximation，SAE）；(iv) 氦阳离子（He⁺）的精确一维描述。
