K shell parameters of some lanthanide elements using bremsstrahlung

The spectrum of external bremsstrahlung (EB) transmitted through Tb and Ho is measured using a HPGe detector spectrometer. A sudden drop in transmitted intensity at K shell binding energy has been used to determine the K shell photoelectric parameters. The unwanted characteristic K x-ray photons gen...

Description
Summary:The spectrum of external bremsstrahlung (EB) transmitted through Tb and Ho is measured using a HPGe detector spectrometer. A sudden drop in transmitted intensity at K shell binding energy has been used to determine the K shell photoelectric parameters. The unwanted characteristic K x-ray photons generated just below the K edge has been avoided by carrying out a separate experiment in the same geometry. The measured values of K shell parameters have been compared with FFAST values. •Bremsstrahlung attenuation in Tb and Ho targets is measured.•At K edge a sharp decrease in intensity is used to determine the K shell parameters.•The K x-ray photons appear just below the K edge hinders the precise measurement.•This hindrance is avoided using monochromatic gamma source.•Measured values are compared with those obtained from FFAST tabulations.
