Femtosecond wave-packet dynamics studied by time-resolved zero-kinetic energy photoelectron spectroscopy

Abstract
Femtosecond pump–probe zero‐kinetic‐energy (ZEKE) photoelectron spectroscopy is studied using the known wave‐packet dynamics of I2 (B state). The 340 fs wave‐packet period, wave‐packet dephasing and rephasing are observed in the ZEKE signal. The effect of various laser and ZEKE parameters on the wave‐packet dynamics is discussed.
