李敬萱教授

Ph.D.,Texas A&M University, USA (1983)

研究領域：原子、分子物理〔實驗〕

以離子束(H2+,H3+,He+,Ca2+,Ar+)或質子(H+)束探測氣體或金屬表面的結構，藉由光譜的分析(如:圖一,二,三)我們可以瞭解這類碰撞的散射截面積、電荷交換的情形，和經由碰撞而產生的濺射離子或原子速度分佈與入射的離子的關係。

本實驗室目前備有:

(1) Duplasmatron ion source (5 KeV - 30 KeV)

(2) Coulotron ion source ( 1 KeV - 10 KeV )

(3) Vacuum chamber ( ~5*10E-10 torr )

(4) Spectrometer ( arc 1 m)

(5) Data Acquisation system
