4-topshiriq 1. Elastik va noelastik sochilishlaming asosiy farqi nimada?
2. Sochilishning differensial effektiv kesimini izohlab bering.
3. Masala. Born yaqinlashishida U = -|U0| agarda r < R yoki U = 0 agar r>R bo’lganida sferik potensial o‘radagi sochilishning amplitudasi va differensial kesimi hisoblansin
4.Masala. Oldingi masaladagi sochilishning differensial kesimi natijasidan foydalanib potensial o‘ra orqali sodir boladigan sochilishning to‘liq differensial kesimi aniqlansin. Quyidagi ikkita chekli hollar ko‘rilsin:
a) k R » l , ya’ni tezligi katta bo‘lgan zarrachalaming sochilishini;
b) k R « 1, ya’ni tezligi kichik boigan zarrachalaming sochilishini.
