Measurement of the anisotropy parameters for the M X-rays of gold induced by 3–9 MeV carbon ions

The angular distribution of Au M X-rays induced by 3–9 MeV carbon ions has been measured with a Si(Li) detector and found to be strongly anisotropic. The measured values of the anisotropy parameters range between 10% and 38%. The implication of such high values of the anisotropy parameter for M X-ray production cross section measurements has been discussed.
