naturally occurring Isotope and their abundance

[math]{138 \atop\; }Ba(72%), {137 \atop\; }Ba(11%),{136 \atop\; }Ba (7.9%), {135 \atop\; }Ba(7%), {134 \atop\; }Ba(2%)[/math]

Single neutron knockout

[math]{137 \atop\; }Ba (\gamma,8){136 \atop \; }Cs[/math]

Single proton knockout

[math]{137 \atop\; }Ba (\gamma,p){136 \atop \; }Cs[/math]

Neutron Separation Energy= Energy needed to liberate a neutron from the Nucleus

=[math]S_n = B({138 \atop 56} Au_{118})-B({{136} \atop 55} Au_{117})[/math]
[math]\left [79(1.007825 u) + 118 (1.008665 u) - 196.97 u\right ] \frac{931.5 MeV}{u} -\left [79(1.007825 u) + 117 (1.008665 u) - 195.967 u\right ] \frac{931.5 MeV}{u}[/math]
[math]=\left [(1.008665 u) - 196.9665516 u+ 195.9665513 u\right ] \frac{931.5 MeV}{u} = 5.3 MeV[/math]
