PACS
PACS is the Physics and Astronomy Classification Scheme®. PACS numbers,
developed by the American Institute of Physics, have been used in Physical
Review since 1975 to identify fields and sub-fields of physics. (PACS codes
from the Acoustics Appendix are not included in some of the formats listed
below.)
- PACS Category 00: General
- PACS Category 10: The Physics of Elementary Particles and Fields
- PACS Category 20: Nuclear Physics
- PACS Category 30: Atomic and Molecular Physics
- PACS Category 40: Electromagnetism, Optics, Acoustics, Heat Transfer, Classical Mechanics, and Fluid Dynamics
- PACS Category 50: Physics of Gases, Plasmas, and Electric Discharges
- PACS Category 60: Condensed Matter: Structure, Mechanical and Thermal Properties
- PACS Category 70: Condensed Matter: Electronic Structure, Electrical, Magnetic, and Optical Properties
- PACS Category 80: Interdisciplinary Physics and Related Areas of Science and Technology
- PACS Category 90: Geophysics, Astronomy, and Astrophysics
- Appendix to 43: Acoustics
