Decay mode

Chart files for Isotope Explorer

Decay mode

File name: $decmode.chr

Displays decay mode of the nuclides. The chart is color-coded according to decay mode variable DecayMode:

0: Stable
1: EC (includes Beta+)
2: Beta-
3: Beta-
4: EC + Beta-
5: Alpha
6: Alpha + EC
7: Alpha + Beta-
8: Alpha + Beta- + EC

The nuclide boxes are linked to the ENSDF database.

Requirements

If you want to access ENSDF data via the chart, the ENSDF database must be available on disk or CD-ROM.

// Determine decay mode from TOI.DAT

// calculate total decay percent:

Def(TotDecay=if(IsDef("%A")+IsDef("%B-")+IsDef("%EC"),\

val("%A")+val("%B-")+val("%EC")+val("%B+"),"%A")

Def(Unstable=LT("t1/2s",0.9e+20)) // definition of "stable" nuclei

// calculate code for decay mode:

Def(DecayMode=unstable*(4*IsDef("%A")+2*IsDef("%B-")+IsDef("%EC")+1))

ColorAccordingTo(DecayMode) // color on decay mode

// get values for nuclide boxes:

FindOut(TotDecay)  

FindOut(t1/2)

FindOut(%b-)

FindOut(%ec)

FindOut(%b+)

FindOut(%A)

FindOut(DecayMode)
