چکیده

در این پژوهش، برای نخستین بار در کشور، جداسازی لیزری ایزوتوپ C¹³ از راه گسست چندفوتونی ایزوتوپ- گزین مولکول‌های گاز HCl₂CF در مقیاس آزمایشگاهی به انجام رسید. برای این کار، تپ‌های یک لیزر ₂TEA CO کوک‌پذیر که با یک برشگر پلاسمایی کوتاه‌سازی شده‌اند، با شاریدگی ²J/cm 50 درون اتاقک تابش‌دهی کانونی شدند. اتاقک تابش‌‌دهی نیز با فشار mbar 10-20 از گاز HCl₂CF با نسبت‌های HCl: He₂CF برابر 1:5 و 1:10 پر شده بود. نشان داده شد که فراوانی ایزوتوپ C¹³ در فرآورده‌ی گسست ₄F₂C با کاهش فشار گاز و شمار تپ‌های لیزری فرودی افزایش می‌یابد. در این آزمایش‌ها، بیشینه‌ی فراوانی ایزوتوپ C¹³ به‌دست آمده در آمیزه‌ی گازی با نسبت HCl: He₂CF برابر 1:5 و فشار HCl₂CF برابر mbar 10 به‌دست آمد که با 1500 تپ لیزری با شاریدگی ²J/cm 50 تابش‌دهی شده بودند.

چکیده [English]

In this work, laboratory-scale laser isotope separation of ¹³C by isotope-selective multi-photon dissociation of CF₂HCl gas molecules has been done. To do this, the pulses of a tunable TEA CO₂ laser, which have been shortened using a plasma shutter, were focused inside the irradiation cell with fluence in 50 J/cm². The irradiation cell was filled with 10-20 mbar of CF₂HCl gas with CF₂HCl:He ratio of 1:5 and 1:10. It has been shown that the abundance of ¹³C in C₂F₄ product of dissociation increases with decreasing of the gas pressure and the number of the incident pulses. In these experiments, the highest abundance of ¹³C isotope was obtained with CF₂HCl: He ratio of 1:5 and ten mbar pressure of CF₂HCl gas, irradiated by 1500 pulses with 50 J/cm² fluences.
