Chart data for Isotope Explorer
There are two kinds of files that can be used to produce nuclear charts:
- Chart data files (.dat files)
- These files normally contain a lot of data that can be loaded into a chart. The
default .dat file is toi.dat (see below). The file toi.dat can be used with an
empty .chr file. Other .dat files are initialized by including
the command Database(filename) in the build section of a .chr file
- Chart files (.CHR files)
- Stand-alone chart files, normally containing a small selection of properties
Data files with extension .dat
Download a file by shift-clicking the file name. The files
should be placed in the same directory as the Isotope Explorer program.
- Ground-state properties, toi.dat
- These are data mainly from the Table of Isotopes
(detailed description)
- Möller-Nix theory, moller.dat
- **** Reference, short description
**** What is the unit of Sn in the Moller database? The numbers
look very strange!!! ***** (detailed description)
- Decay parents and daughters, decay.dat
- This is a special data file that contains parents and daughters
of all nuclides. This file is needed for showing decay chains (acivated
by the decay button in the tool bar)
Chart files with extension .chr
The chart files can either be used as they are or they can be
modified to fit your needs. To modify a file, download it to your
hard disk, make the appropriate changes with any editor and save it.
Launch Isotope Explorer, open the chart file and click the Build Chart
button in the tool box. Searching through a large part of the ENSDF
database may take a few minutes, but you should consider the alternative
of doing the same by hand! Have a cup of strong coffee while you wait!
Note that some chart files require ENSDF data (ENSDF, PENSDF or SENSDF)
on disk in order to work properly.
If you have set the extension .chr to launch Isotope Explorer as a helper
application, you can launch it by clicking the file name. Alternatively,
you can transfer a file by shift-clicking it, and open it in Isotope
Explorer with File, Open Chart or clicking the Chart button.
- Beta stability: $bstab.chr
- Access to ENSDF data. Requires ENSDF data (ENSDF) on disk.
The chart is color-coded according to the EC or beta- Q-value
(detailed description)
- Decay data: $decay.chr
- Chart interface for decay data. Requires decay data (PENSDF) on disk.
The chart is color-coded according to the natural abundance
(detailed description)
- Decay mode: $decmode.chr
- Displays decay mode of the nuclides. Requires ENSDF data (ENSDF) on disk.
The chart is color-coded according to decay mode
(detailed description)
- Find a decay gamma: $findgam.chr
- Template for a script to find a decay gamma
of a given energy. Requires decay data (PENSDF) on disk
(detailed description)
- Isomers: $isomers.chr
- Chart interface for isomeric states. Requires ENSDF data (ENSDF) on disk.
The chart is color-coded according to the number of isomeric states
- here defined as a state above the ground state with a half-life of more than 1 microsecond
(detailed description)
- Superdeformed band data: $sd.chr
- Chart interface for SD band data. Requires SD data (SENSDF) on disk.
The chart is color-coded according to the number of known SD bands in each nuclide
(detailed description)
- Weizäcker's mass formula I, $kranem.chr
- The chart is color-coded according to the difference between the
calculated and experimental binding energy per nucleon
(detailed description)
- Weizäcker's mass formula II, $cupsm.chr
- The chart is color-coded according to the difference between the
calculated and experimental binding energy per nucleon
