Lithium isotope with 3 neutrons

WebThe isotopic composition of lithium from naturally occurring minerals is 7.5% 6 Li and 92.5% 7 Li, which have masses of 6.01512 amu and 7.01600 amu, respectively. A commercial source of lithium, recycled from a military source, was 3.75% 6 Li (and the rest 7 Li). Calculate the average atomic mass values for each of these two sources. 25. WebFor fast neutrons, its cross-section is on the order of barns. Boron, as the neutron absorber, has another positive property. The reaction products (after a neutron absorption), helium and lithium, are stable isotopes. Therefore there are minimal problems with decay heating of control rods or burnable absorbers used in the reactor core.
