Расчётное уточнение исходной сейсмичности на примере территории г. Салават, Республика Башкортостан

In course of the study, an analysis of the regional earthquake catalogues, issued by different institutions, was fulfilled providing the basis for determination of the seismic regime parameters and regional macroseismic equation on the area of investigation. The obtained data made it possible to calculate the corrected value of general seismicity rate for territory of the city of Salavat, Bashkortostan.В ходе работ выполнен анализ региональных сейсмических каталогов, предоставленных разными агентствами, на основании чего были получены параметры сейсмического режима и региональное макросейсмическое уравнение для исследуемого района. Полученные данные послужили основой для расчета уточненного значения исходной сейсмичности для территории города Салават, Республика Башкортостан

Time-Resolved Luminescence of LaBr3\mathrm{LaBr_3}-Ce Scintillation Crystals Upon Selective UV-VUV-XUV Excitation

The time-resolved photoluminescence (PL) of LaBr3-Ce scintillation spectrometric crystals produced in Russia is measured upon excitation using synchrotron radiation with photon energies of 3.7-21 and 45-290 eV at temperatures of 295 and 7.5 K. The PL spectra and decay curves are measured for excitation in the transparency range, at the edge of fundamental absorption, at the interband transitions, and in the range of inner-shell absorption. It is demonstrated that the PL yield is not proportional to the excitation energy, and that the PL decay curves are modified in the range of photoionization of the 3d (Br) and 4d (La) inner shells and, especially, in the range of giant resonance. © 2013 Allerton Press, Inc
