The process of excitations of the glutamine molecules in the gas phase during collisions with low-energy electrons (0–70eV) for samples before and after irradiation (11.5MeV) at the M-30 microtron with doses of 10 kGy have been investigated by the optical spectroscopy method. Optical spectra were studied in the wavelength range 200–520nm; the effects caused by both external radiation and the scanning electron beam with the 30, 50, and 70eV energy were investigated. For the most intense emission of the molecular fragments, their thresholds and excitations’ energy dependences were determined in the range of electron energies up to 30eV. The new effect has been established: for λ > 310nm, the irradiated samples’ emission increased both by increasing the scanning beam’s electron energy and the emitted light wavelength. However, for values of λ < 310nm, there is an opposite dependence. The simulation of the glutamine transformations under irradiation was carried out within the method of structural combinations, which allows determining all sets of molecular structures of glutamine without and in the presence of ‘broken’ chemical bonds. The role of radiation in the formation of metastable molecular structures, which determine the features of the optical and mass spectra of irradiated glutamine samples, is investigated.

已经研究了在 M-30 微加速器以 10 kGy 剂量照射之前和之后（11.5MeV）样品与低能电子（0-70eV）碰撞期间气相中谷氨酰胺分子的激发过程。光学光谱法。在 200-520nm 波长范围内研究了光谱；研究了由外部辐射和能量为 30、50 和 70eV 的扫描电子束引起的影响。对于分子碎片的最强烈发射，它们的阈值和激发的能量依赖性在高达 30eV 的电子能量范围内确定。新的效应已经建立：对于λ> 310nm，通过增加扫描束的电子能量和发射光波长，照射样品的发射增加。然而，对于λ < 310nm 的值，存在相反的相关性。辐照下谷氨酰胺转化的模拟是在结构组合方法中进行的，这允许在不存在和存在“断裂”化学键的情况下确定谷氨酰胺的所有分子结构集。研究了辐射在亚稳态分子结构形成中的作用，亚稳态分子结构决定了受辐照谷氨酰胺样品的光学和质谱特征。
