e.g. 22 Na. The spectrum will show a gamma-ray at 1274.5 keV, an annihilation peak at 511 keV (from the b +) and probably x-rays from the electron capture. 22 11 Na 11 22 11 Na 11 1cay Scheme De Na-22 disintegrates predominantly to the 1275 keV level of Ne-22 .

The decay scheme of the nuclide 11 22 Na with a 2.6-year half-life serves as an example (see Fig. 1.19). The 11 22 Na nuclides decay by both electron capture

Wikimedia Commons In the [sup 31]Na decay, the assignment of previously reported [gamma] transitions and the observation of a new level at 3760 keV lead to a revised decay scheme which is found in good agreement 2016-11-05 · In the picture on the left you see the scheme of cesium decay in which the maximum energy of the electron is shown which corresponds to about 500KeV. As a sample for measurement was used a sample source of 0,25uCi.
