Chart files for Isotope Explorer

Find a decay gamma

This is a template to search for decay gammas of a certain energy. The chart has to be build (click on the Build Chart button in Isotope Explorer)

In this example we know that the gamma-ray energy is 1001.0 +- 0.5 keV, and that is is present in the ²³⁸U decay chain. After the energy search (limited to A=206-238), this piece of information can be used in the following way:

1. Select the decay button in the tool bar of Isotope Explorer
2. Click the ²³⁸U box
3. The program will trace out the ²³⁸U decay chain, and it is obvious that the gamma is in the decay of ²³⁴Pa
4. Double-clicking the ²³⁴Pa box will bring up the decay scheme. Notice, however, that there are three data sets for the decay of ²³⁴Pa, and the 1001.03 keV gamma-ray can be found in the 1.17 m beta- decay
