Body text

In this solution, energy distribution and time spectra of internal from 57Fe were measured. The emission signal of conversion electrons excited with incident X-ray photons was discriminated by electron energy analysis and intense prompt noise was excluded in the signal processing. The analyzer was a planar electrostatic quadrupole type which realized the energy resolution of 4% corresponding to the escape depth of 20 nm. These data suggest the possibility of depth sensitive nuclear inelastic scattering by electron detection.
