This project involves development of the Advanced Physics Laboratory course to allow undergraduate students to study select topics from atomic, molecular, and solid state physics and learn the methods of modern experimental techniques. A computer-interfaced optical spectroscopy system (spectrophotometer) is helping to develop three new experiments on atomic physics, molecular physics, and quantum mechanics. The experiments are measuring the Rydberg constant, isotope structure, and fine structure for the atomic transitions in hydrogen, the molecular optical transitions of N2, and the energy gap of silicon, germanium, and gallium arsenide. Students can greatly benefit from training on the computer-interfaced, high-resolution equipment, while learning essential laws of physics.

本计划包括发展高等物理实验课程，让本科生学习原子、分子和固态物理的特定主题，并学习现代实验技术的方法。计算机接口光学光谱系统（分光光度计）正在帮助开发原子物理、分子物理和量子力学三个新的实验。实验测量了氢原子跃迁的里德伯常数、同位素结构和精细结构，N2的分子光学跃迁，硅、锗和砷化镓的能隙。在学习基本物理定律的同时，学生可以从计算机界面、高分辨率设备上的训练中受益匪浅。
