Lithium 7 nucleus (stable)
Nuclear structure of

Beryllium 7 

(half life = 53.22 d) when mouse off the image. Move mouse on image for Li7 nucleus.

Blue toruses = 7 protons
Red toruses = electrons, yes, 3 nuclear electrons

Atomic number of Be (4) = protons (7) - nuclear electrons (3)

Beryllium 7 transform by K electron capture of
Beryllium 7 and Lithium 7 produced: Be7 + e- = Li7

(K electron capture can only occur at the end of the nuclear nanotube, NOT into the central part of proton rod of nucleus).

Irradiation of Be7 with gamma rays near energy of pair production may cause perhaps prompt positron emission in consequence of Beryllium 7 isotope nuclear electron capture. Artificial influence of nuclear reactions may resulted. No need of exact frequency for gamma rays I think, because nuclei may compensate the required energy.
