II.    Office Schedule


        Wednesdays:   KAIST all day

                Office:     Physics/5308

                Phone:     869-8424 (KAIST)

        Otherwise:       KAERI (042-868-8718)



III.   Course Objective


        A:    How to calculate


                Energy levels and wavelengths


                Transition probabilities and lifetimes

                Electron-impact excitation cross sections for neutral atoms


                Atomic and molecular ionization cross sections


        B.    Applications


        Basic science: Atomic spectroscopy is the most accurate branch of physics (8 significant figures, if necessary)


        To discover new effects:  The Lamb shift is one the best examples.


        Astrophysics:  Light is the only means of observationatomic/molecular spectroscopy, transition probabilities


        Fusion plasma modeling:  Diagnostics now, and when a reactor becomes reality, then improve reactor efficiency


        Plasma processing:  Fabrication of semiconductors, materials coating, rocket design, atmospheric science


        Radiation monitoring:  Radiation protection, medical applications


C:    Tools


        Computer codes for structure and collision are usually separate.  MCDF2002 has begun to integrate capabilities to calculate wave functions and use them to calculate some collision cross sections.


        In this course, we will learn how to run MCDF2002 on a windows-based (98/2000/XP) PC.


IV.   Where are the centers of active research in atomic structure and collision, both theory and experiment?




        US, UK, France, Japan, Russia




        US, Germany, Sweden, Japan, Eastern Europe


V.    National Inst. of Standards & Technology (NIST)


        Established 1902 (Oldest national lab.)


        3000 employees (1500 PhDs)


        Located in Gaithersburge, 40 km northwest of Washington, DC


        Branch (NIST West) in Boulder, Colorado


        Bridge between basic science and industry


        Part of the Department of Commerce, US Government


        Formerly known as the National Bureau of Standards (NBS)


VI.   Research Support in the United States


        National Science Foundation (NSF):  Universities


        Department of Energy (DOE):  National labs, universities, industry


        National Aeronautics and Space Administration (NASA):  National labs, universities, industry


        Department of Defense (DOD):  National labs, industry, universities


VII.  American Physical Society (APS)


        Many divisions according to specialties


        The largest is the Condensed Matter Physics Division


        Atomic physics is included in the Division of Atomic, Molecular, and Optical Physics (DAMOP).


        Divisional meetings are much more popular than the parent organization.
