Calculated the quadrupole electrical transmission |M(E2)|2 W.u ↓ for even-even nuclides of strontium (78-100Sr and 66-76Ge)

By using the half life time for strontium ( 78-100Sr) and (Germanium 66-76Ge) isotopes for even-even from Ferston we calculated the electric quadruple transition and find the relation between number of neutron and |M(E2)|2 W.u ↓ for gamma ray from 2+ to 0+. When calculating the theoretical value of the energy state (first and ground) and the current work of the transition probability (T) and the mean life time (τ (s)) of an isotope of strontium, The theoretical value of the energy state (first and ground) and the current action of the transmission force |M(E2)|2 W.u ↓ by calculating the theoretical value of the total width for gamma decay and calculating the Weisskopf Γ(E2)w.u energy (the Weisskopf single -particle widths ), which is included in the equation where depend on Eγ calculated in keV and A is the mass number. The results were tabulated, discussed and drawn, as it was found that the value of |M(E2)|2 W.u ↓ is the lowest possible at the magic number of neutrons is equal 50, and the values increase as we move away from the magic numbers, that is, when the nuclei are saturated, regardless of the number of protons, which play an important role for the same subject and for even-even nuclei.
