, ΔI (ΔP) – spin (parity) difference between initial and final states, α – see Table.

α–values
	ΔI = 0	ΔI = ±1	ΔI = ±2	ΔI = ±3	ΔI = ±4
ΔP=1
ΔP=-1
g.s. → g.s. allowed beta transitions (recommended in the case of uncertain spectroscopic data)

Caution! Results are extemely sensitive to structure (spin, parity) of initial and final states! Check and edit, if necessary.
