“…X-ray spectra provide us the important information on issues such as the vacancy transfer probabilities, production cross sections, estimation of the effects of the valence electron structure and chemical environment on the intensity ratio, as well as the element contents (Gójska et al, 2020). Therefore, the K shell X-ray intensity ratios of 3d metals have been investigated by many of investigators (Alım et al, 2016;Garmay et al, 2017;Gójska et al, 2020;Perişanoğlu & Demir, 2015;Perişanoğlu et al, 2020;Uğurlu et al, 2019;Uğurlu et al, 2017).…”

Bu araştırmada, Ni-B alaşımlı kaplamalarda Ni'nin K kabuğu değerlik elektronik yapısı, X-ışını emisyonu ve XRD spektrumları toplanarak incelenmiştir. Elde edilen veriler K beta/K alfa X-ışını yoğunluk oranları ve XRD verileri açısından değerlendirildi. Kaplanmış alaşımlar, bu çalışma için farklı konsantrasyonlarda altıgen bor nitrür (hBN) kullanılarak elektrokimyasal depolama yöntemiyle üretilmiştir. Mevcut örneklere sabit konsantrasyonda sakarin ve trimetilamin boran kompleksi (TMAB) ilave edildi. Mevcut örnekler, 241 Am halka şeklindeki radyoaktif kaynaktan gelen 59.5 keV fotonları tarafından uyarıldı. Örneklerden yayılan K kabuk X-ışınları, 5,9 keV'de 150 eV çözünürlüğe sahip bir Ultra-LEGe dedektörü vasıtasıyla tespit edildi. Ni-B alaşımlarının K kabuğu X-ışını yoğunluk oranları saf Ni ile kontrol edildi. Mevcut sonuçlardaki değişimler, katkılı TMAB ve sakarin içeren Ni-B/hBN kaplama malzemelerinde Ni'nin değerlik elektronik yapılarındaki değişim ile yorumlanmıştır.

“…The literature contains many studies regarding the calculation of Z ef f of alloys using attenuation or scattering methods. Transmission condition or geometry, based on attenuation of * Correspondence: mehmet.buyukyildiz@yalova.edu.tr photons, has been widely used to determine Z ef f of alloys [2][3][4][5][6][7][8][9][10][11][12][13]. On the other hand, the Rayleigh-to-Compton scattering ratio is a nondestructive technique that provides useful data about the crystal structure and physical properties of materials and is based on the measurement of Rayleigh and Compton scattered photons emerging from the sample of composite material in a suitable source-sample-detector arrangement.…”

Abstract:The aim of the present study is to determine effective atomic numbers ( Z ef f ) of Fe x Cu 1−x binary ferroalloys using scattering of 59.54 keV gamma photons at 130• ( x = 4.36Å −1 ) scattering angle. For this purpose, the Rayleigh ( R) and Compton ( C) scattering intensities for the given alloys were measured using a monoenergetic beam of 59.54keV gamma rays and the Rayleigh-to-Compton scattering ratio R/C was determined. Then the Z ef f values of these alloys were determined by interpolating the R/C of the material using the R/C data of adjacent elements in between the R/C of the alloys. For comparison, Z ef f s of alloys were also calculated using direct and interpolation methods in term of scattering R/C and attenuation of gamma photons. Good agreement in relative differences between Z ef f s (experimental and theoretical) was found (maximum of ≤ 3.3% for total att.-direct method) for the chosen alloys and the Rayleigh-to-Compton scattering ratio was shown to be a complementary approach to determine the effective atomic number of binary ferroalloys. In addition, a polynomial equation between the experimental R/C values and the mass attenuation coefficients of alloys was developed to estimate the mass attenuation coefficient of different materials.
