Abstract:
The photoelectric effect has been seen in the past as an instantaneous 
process.
Due to our recent attosecond-time resolved photoemission experiments we have
measured that the photoelectric effect is not instantaneous, photo-electrons
emitted from different bands and states leave delayed at different times.
The talk reviews the status of this recent development and presents very new
and not yet published results. Furthermore the relationship between those time
delays and phase shifts measured by means of spin resolved measurements
is also discussed.
