International Collaboration

1.    Advanced Light Source, Lawrence Berkeley Lab, Berkeley, USA    

The collaboration started in June 1996 and continuing. It grants access to the world’s best synchrotron radiation facility in the soft x-ray regime. We carry out high-resolution XPS and XANES studies using a Beam Line dedicated for photoemission studies.
