Chart Data for Isotope Explorer 2.0

Chart Data Files (.dat files)

The following chart databases have been provided.
toi.dat (default) containing experimental ground-state and isomer properties from the Table of Isotopes.
Moller.dat containing calculated ground-state properties for about 9000 nuclides calculated by Møller et al, LANL Report LA-UR-94-3898 (1994).
Decay.dat containing parent-daughter relationships for all nuclides. This file is activated by the decay button on the tool bar.
Additional databases can be generated by the user (see manual).

Chart files (.chr files)

These files contain scripts for generation charts from the chart databases and the ENSDF file. The chart button in Isotope Explorer launches the menu of available charts (.chr) files. The scripts can also be edited (see manual) to generate new charts. Two files, blank.chr and blankm.chr, will open generic charts based on the Table of Isotopes (TOI) and Moller databases respectively. The user can then use the select field button to choose data for display on the chart and build its database. The color scheme button allows the user to select a field and setup a color scheme representing its values on the chart. Alternately, the legend can be clicked on to set the data ranges and colors individually. A Chart Wizard is under development to simplify chart generation and will be available with future versions of Isotope Explorer.

The following sample charts are available from the chart file menu.

Half-life chart (toihalf.chr) a chart colored by half-life (seconds) from the Table of Isotopes
Half-life chart (molhalf.chr) a chart colored by half-life (seconds) calculated by Moller et al
Beta-, EC-, and Alpha-decay branchings(decay.chr) a chart colored by decay branching intensities from the Table of Isotopes
Nuclear spin and parity chart (jpi.chr) a chart colored by Spin and parity from the Table of Isotopes
Neutron separation energy chart (toisn.chr) a chart colored by neutron separtation energy from the tables of Audi et al
Beta2 deformtation(molb2.chr) a chart colored by beta2 deformation calculated by Moller et al
ENSDF datasets(dataset.chr) a chart colored by the number of ENSDF datasets for each isotope. This chart containts the dataset names and can be used to open the individual datasets in Isotope Explorer
Gammas with E=1200-1250 keV(findgam.chr) a chart colored by the number of gammas for each isotope with E=1200-1250 from the Adopted Gammas of ENSDF. This chart is an example of a nuclear data search with Isotope Explorer. Liquid-drop model binding energies (binde.chr) a chart colored by the difference between experimental atomic binding energies, from Audi et al, and binding energies calculated with the liquid-drop model using Isotope Explorer
Liquid-drop model (Weizsacker) model masses (masscal.chr) a chart colored by the difference between atomic masses (MeV) from Audi et al and atomic masses calculated with the liquid-drop model using Isotope Explorer.
