Abstract

 We have investigated with unprecedented levels of detail, processes and
 phenomena involving K-shell photodetachment of negative ions and inner-shell 
 photoionization of molecules using the brightness, spectral resolution, tunability and 
 polarization of the Advanced Light Source at Lawrence Berkeley National 
 Laboratory. During this seminar, investigations carried out in K-shell 
 photodetachment of fundamental atomic targets such as Li (1),  He(2) , 
 and C (3) as well as updates on more recent theoretical and experimental development 
 will be discussed. These fundamental systems exhibit a rich structure differing 
 substantially from corresponding processes in neutral atoms and positive 
 ions, owing to the dominance of correlation in both the initial and final states. 
 We will also report on recent studies of photofragmentation dynamics of small clusters.
