Free Access to Databases on Atomic and Molecular Data provided by NIFS:

• Access to NIFS Database

• Example of Numerical Atomic and Molecular Database

  • AMDIS (Atomic and Molecular Data Interactive System)
    In this database AMDIS, theoretical and experimental (obtained with the beam techniques)cross sections for excitation and ionization processes of atoms, ions and some moleculesby electron impact are filed together with the references.

  • SPUTY (Sputtering Yields of Solids by Ions)
    Experimental sputtering yields for monoatomic solids by ions are filed, together with the reference. An empirical formula for calculating the sputtering yields is also included.

  • CHART (Charge Transfer between Atoms and Ions)
    Experimental cross section for chage transfer of ions in collisions with atomic and molecular hydrogen targets are filed together with the references.

  • BACKS (Backscattering Coefficients of Ions)
    Experimental and simulation data for the backscattering coefficients of light ions (H, D and He ions) from monoatomic solids are stored as a function of the incident energy.

  • AMOL (AMDIS-molecule)
    Cross sections and rate coefficients for electron - molecule collision processes

  • CMOL (CHART-molecule)
    Cross sections and rate coefficients for heavy particle - molecule collision processes
