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 Be7 = protons (7) - nuclear electrons (3) = (4), with structure D He3 D

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. The s electrons of K shell are positioned along the axis of the 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.
