Feynman Diagram Electron Scattering

A precise hand-drawn-style Feynman diagram on a chalk-white background illustrating Møller electron-electron scattering (t-channel). Two solid straight fermion lines enter from the lower-left (labeled "e⁻" at each tip with thin serif text); they exchange a wavy virtual photon line (labeled "γ" at the midpoint vertex) and exit toward the upper-right. The vertex junction dots are solid black circles. Time axis runs left to right with a thin dashed arrow along the bottom labeled "Time →"; momentum axis is vertical, labeled "p". A small equation below reads: "M ∝ e²/q²". All lines are 1.5 pt black on white; the wavy photon line uses a fine sinusoidal wiggle. Caption area at bottom: white rectangle with 7 pt sans-serif text "Møller scattering: e⁻e⁻ → e⁻e⁻". The overall aesthetic mirrors a printed physics lecture note, clean and authoritative.

一幅精准手绘风格的费曼图，展示 Møller 电子-电子散射（t 道）。白色背景。两条实直线费米子线从左下进入（端点标注衬线字体 「e⁻」），通过中间顶点交换一条波浪虚光子线（顶点标注 "γ"），向右上方出射。顶点为实心黑圆点。底部细虚线箭头标注 「γ」，纵轴标注 「这是一条示例内容。」。下方小公式："M ∝ e²/q²"。底部白色说明栏，7 pt 无衬线字体：「费曼图电子散射图解」。整体风格类似印刷物理讲义，简洁权威。
