The eigen states whose energy separation is smaller than the life time broadening has been considered to be inseparable with conventional high-precision spectroscopies. The purpose of this work is the development of the conceptually new spectroscopy to resolve these states with applying wavepacket interferometry to short lived electronically excited states. Though the high precision interferometer for the demonstration has been constructed, actual tests have not been executed because I have changed the institute. Then, more efficient systems for the demonstration have been searched with a theoretical collaborator.

能量分离小于寿命展宽的本征态被认为与传统的高精度光谱学密不可分。这项工作的目的是开发概念上新的光谱学，通过将波包干涉测量应用于短寿命的电子激发态来解析这些状态。虽然演示用的高精度干涉仪已经建成，但由于换了机构，还没有进行实际测试。然后，与理论合作者一起寻找更有效的演示系统。
