Method of reflectorβ reflection

A method of reflector reflection is proposed which permits repeated reflection on radiation when only a single surface of the test object is accessible for measurements; it involves the introduction into the gap between reflections from the test object of an auxiliary reflection from a lead or bismuth plate. Experiments are reported which show that the energy and intensity of the reflector reflection are sufficient for detection and that the intensity has a nearly quadratic dependence on the atomic number Z. Instruments are described for analysis by this method.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, Vol. 12, No. 6, pp. 111–115, June, 1969.The author thanks Professor A. A.
