В статье представлены результаты исследования процессов радиационного дефектообразования в монокристаллах фторида кальция под воздействием облучения рентгеновскими лучами, протонами и быстрыми тяжелыми ионами Xe132 и Bi209. Основным методом исследования является абсорбционная спектроскопия. В спектрах оптического поглощения облученных разными видами ионизирующей радиации образцов CaF2 регистрируются широкие интенсивные полосы поглощения, связанные с электронными и дырочными центрами окраски и их агрегатами. Анализ спектров оптического поглощения произведен в координатах Тауца и Урбаха. Выявлено в количественном плане влияние облучения быстрыми тяжелыми ионами на край фундаментального поглощения и на разупорядочение в анионной подрешетке кристалла CaF2. Обсуждена природа радиационно-индуцированного оптического поглощения в области 9,8 эВ, индуцируемого облучением ионами Xe132 и Bi209 .

This paper presents the results of a study of radiation defect creation processes in Calcium Fluoride single crystals irradiated with X-rays, protons, and fast heavy ions of Xe132 and Bi209. The main method of the study is absorption spectroscopy. In the optical absorption spectra of CaF2 samples irradiated with different types of ionizing radiation, broad intense absorption bands associated with electron and hole color centers and their aggregates are recorded. The analysis of the optical absorption spectra is performed in the Tauc and Urbach coordinates. The effect of fast heavy ion irradiation on the fundamental absorption edge and on disordering in the anion sublattice of the CaF2 crystal is quantitatively revealed. The nature of the radiation-induced optical absorption in the 9.8 eV region induced by irradiation with Xe132 and Bi209 ions is discussed.
