Abstract: | The effect of external magnetic field on the Kα
and Kβ X-ray production cross-sections and K shell fluorescence
yields for ferromagnetic elements Nd, Gd and Dy and paramagnetic elements Eu
and Ho have been measured at the excitation energy of 59.5 keV γ
-rays from 241Am radioactive source of strength 100 mCi in the
external magnetic field of intensities ±0.75 T. Furthermore,
IKβ /IKα intensity ratios for these elements have been
measured in the external magnetic field. The K X-rays from different targets
were detected using a high resolution Si(Li) semiconductor detector. For B = 0, the measured K X-ray production cross-sections,
K shell fluorescence
yields and the IKβ /IKα intensity ratios were compared
with the experimental and theoretical data in literature. The results have
shown that the fluorescence parameters as photoionization cross section,
fluorescence yield, radiation rates and spectral linewidth can change when
the irradiation is conducted in a magnetic field. |
