Atom fizikasi

Ishning bajarilish tartibi.
1. Qurilmaning tuzilishi va ishlash printsiplari bilan tegishli qo’llanmadan o’rganilgach, uni ishga tayyorlanadi. Analizator, NaJ- detektor tok manbaiga ulanadi va detektorga yuqori kuchlanish beriladi.
2. Manba idishining qapqoqi bektilgan holda FEUni 90^o burchak ostida qo’yib, NaJ kristalli ustiga namunaviy standart gamma-nurlanish manbai (OSGI) qo’yiladi va energetik kolibrovka qilinadi. Energetik kolibrovka qilish uchun kobalьt-60 radiopreparatidan foydalaniladi.
3. FEU ni “o⁰” holatga o’rnatiladi, sochuvchi modda olib qo’yiladi, manba qopqoqi ochiladi va sochilmagan Ss-137 nurlanishning spektri olinadi. Ushbu manba  kvantlarining energiyasi. Ye_  662 keVga teng.
4. FEU ni 20^o burchak otida o’rnatiladi. Sochuvchi modda kiritiladi, manba solingan qo’rg’oshin idishning qopqoqi ochiladi va sochilgan SS-137 nurlanishning spektri olinadi. Olingan spektrdagi cho’qqi markazining holati ya’ni energiyasi aniqlanadi.
5. 4 punktdagi amallar boshqa sochilish burchaklari ( 40^o, 60^o va o^o) uchun ham bajariladi.
6. Tajribada o’lchangan sochilgan  kvantlar energiyalari qiymatini Kompton effekti nazariyasida olingan natijalar bilan solishtiriladi.
