WebMSssbauer spectra were also obtained from samples of the late-maturing (stage III) and early-maturing (stage II) teeth. These spectra showed a lower absorption intensity due to both the smaller amount of sample available and the lower concentration of iron in the teeth at these stages. The immature teeth (stage I) Web24 de mar. de 2024 · The Lorentzian function gives the shape of certain types of spectral lines and is the distribution function in the Cauchy distribution . The Lorentzian function has Fourier transform (9) The Lorentzian function can also be used as an apodization function, although its instrument function is complicated to express analytically.
