“…(3) The ratio between the integral intensities of K~I and K~2, including the satellites, is in good agreement with the theoretical value of 0.513 for the relative X-ray emission rate (Scofield, 1974). Considering only the main peaks, there is, however, a considerable difference for the single-crystal values.…”

Single-and double-crystal spectrometer measurements of the Cu K~ doublet have been carried out after the selection of optimum measurement procedures and parameters. These include the influences of the X-ray-tube arrangement, horizontal and vertical divergences and the slow 0 or 2 dependence of the reflection curve. The influence of the apparatus function on the measured intensity distribution was minimized. The measured intensity profile could be approximated by a convolution of the instrumental function and the spectral line, with the inclusion of two additional terms. The intrinsic spectral line was fitted by Lorentz functions and, thus, described by 12 parameters. Good agreement between the results of the different measuring procedures and those of other authors is obtained. The apparent differences are discussed.

“…(c) In Table 2a, columns 3 and 4, the /3la ratios are satisfactorily close to the 'free atom' values, i.e. 0·183 for Sr and 0·168 for Br (Scofield 1974), and the scatter in the four observations is also acceptable. However, in Table 2b, the /3la ratios differ by several standard deviations from the batch means, and that for Br departs significantly from O· 168.…”

Studies have been made with proton induced X-ray emission to measure bromine in human blood plasma, and thereby estimate the extracellular fluid volume which is a determinant of biological importance. With careful attention to sample preparation, the method is precise. Since only very small amounts (less than O· 1 ml) of material are needed, the technique is applicable to the newborn and to small mammals.

“…Experimental K β /K α X-ray intensity ratios for these elements have been compared with theoretical estimates [25][26][27] and other experimental results [13,28,29]. Theoretical estimates based on relativistic Hartree-Fock and Hartree-Slater theories were calculated by Scofield [25,26].…”

K_β/K_αX-Ray Intensity Ratios for Co, Ni, Cu, and Zn in Phthalocyanines Complexes

The K β /Kα X-ray intensity ratios of Co, Ni, Cu and Zn in metalophthalocyanines complexes have been studied. Co, Ni, Cu and Zn elements have been excited by using 59.5 keV photons emitted by 50 mCi 241 Am radioactive source. K X-rays emitted by samples have been counted by a Si(Li) detector with resolution 0.16 keV at 5.9 keV. We have found that K β /Kα X-ray intensity ratios of Co, Ni, Zn, and Cu complexes have changed depending on chemical structures of Co, Ni, Zn and Cu. The measured values have been compared with the theoretical predictions and experimental values of pure elements.
