Scattering of Ultrashort X-ray Pulses on Diamonds with NV Centers

Abstract

The scattering of ultra-short X-ray pulses (USPs) is an important component of diffraction analysis of matter. Usually, the specific scattering of such USPs is not taken into account to determine the structure of a substance. Taking into account the specifics of scattering on complex structures will give more accurate results when deciphering complex structures. In this work, it is shown that when X-ray USPs are scattered on diamond with NV centers, it is necessary to take into account the pulse duration. The results obtained can be very different from the widely used theory of diffraction analysis, which confirms the need to take into account the specifics of USP scattering when diagnosing complex structures. It is shown that the scattering spectra are very sensitive to the concentration of NV-centres in the diamond structure, and this can be used in diffraction analysis.

“…The main difference between Equation (2) and the previously known theory is determined by the factor γ i,j (p 0 , p τ ), the analysis of which determines the difference between our theory and the previously famous one. As was shown in early works [25,30,31], the difference between the theory presented here and the previously known one is mainly observed when using attosecond and shorter pulses on certain types of structures. Analysis of the parameter γ i,j (p 0 , p τ ) provides a qualitative explanation of the influence of the pulse duration on the scattering spectra.…”

“…Let us define orientation 1, presented in Figure 1; orientation 2 shown in Figure 2; orientation 3 presented in Figure 3; and orientation 4 presented in Figure 4. In the works [24,25,[30][31][32], it was shown that when using the sudden disturbance approximation, it is possible to obtain expressions for calculating scattering spectra taking into account the duration of the incident USP. The special role of the pulse duration during its scattering is determined by attosecond pulses; i.e., such pulses can give a large difference in the scattering spectra when using the previously known theory and the theory developed in these works.…”

“…The diffraction analysis of such structures with ultra-high spatial and temporal resolution is a promising direction in modern physics. Femto-and especially attosecond scattering processes on such structures with time resolution have been little studied and are currently being actively developed [5,7,8,[20][21][22][23][24][25][26][27][28]. Typically, the scattering of X-rays by various periodic and complex structures is described as the scattering of plane monochromatic waves of infinite duration in time [3,29].…”

Peculiarities of Scattering of Ultrashort Laser Pulses on DNA and RNA Trinucleotides

“…Recently, it has been shown in [ 18 , 19 , 20 ] that there are important cases where the specific scattering of USPs must be accounted for in diffraction analysis; consequently, the use of Equations ( 1 ) and ( 2 ) results in significant errors. Basically, such errors appear in the scattering of attosecond USPs on certain kinds of structures.…”
