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?

 

        Theory

 

        US, UK, France, Japan, Russia

 

        Experiments

 

        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.
