Bonjour, je comprend pas comment on résout, l'item B, je crois c'est tout bête, mais la correction c'est : E(beta max) = deltaM * c² = 39,1 keV. Mais je comprends pas comment on a deltaM.image.thumb.png.6ed0ade9b19d6c43344899679cbe1f1b.pngimage.png.4e5f16604dbb5006c8c2cbc8e0d12284.png

@Maeduin salut

On nous demande l'énergie des électrons, donc il s'agit d'une transformation B-. Lors d'une B- c'est du Z+1 donc le 44Ru se transforme en 45Rh.

ΔM = M(Ru) - M(Rh)

       = 105,907328 - 105,907286

       = 0,000042 (uma) x 931 (MeV/c2)

       = 0,0391 MeV/c2

       = 39,1 keV/c2

Donc Emax = ΔM.c2 = 39,1 keV
