Nuclear isomers of half-lives above one second have been excited from the ground state of stable nuclides via inelastic γ-ray
scattering by using bremsstrahlung of a 4 MeV, 22 μA linear electron accelerator. This method is potentially useful for a
number of elements in elemental analysis by virtue of its high specificity and, in some cases good sensitivity. As there is
no need for special sample preparation, this kind of activation may be preferable in some applications. Detection sensitivities
have been determined for 15 elements, and possibilities in routine chemical analysis are discussed.
