Accurate measurements of component wear in service are important for assessment of the component lifetimes and for materials development. A diagnostic method known as the radionuclide marker technique offers promise of providing on-line measurement of wear in various components in which such monitoring was hitherto very difficult and expensive, or impossible. This technique involves activation of a spot on a

X-ray fluorescence (XRF) provides a convenient and accurate means of estimating lead content in bone. However, before one can accurately interpret XRF results to obtain a measurement of lead exposure in either clinical medicine or... more
X-ray fluorescence (XRF) provides a convenient and accurate means of estimating lead content in bone. However, before one can accurately interpret XRF results to obtain a measurement of lead exposure in either clinical medicine or epidemiologic studies, several issues regarding the distribution of lead in the human skeleton and the histomorphometry of bone need to be addressed. 17 refs., 3

We present measured angular distributions for ..pi../sup +/-elastic scattering at 30 and 50 MeV from selected targets with A=12 to 208. These angular distributions were analyzed using a phenomenological optical potential of first-order form. The mass dependence of the potential strength ...
