In Rutherford scattering experiment, what will b ethe correct angle for `alpha` scattering for an impact parameter `b = 0` ?

A

`90^@`

B

`270^@`

C

`0^@`

D

`180^@`

Text Solution

Verified by Experts

The correct Answer is:
D
`b = (ze ^2cot ( theta /2))/( 4 pi in _0 k_i ) = 0 implies cot ((theta )/(2)) =0`
` = theta /2 = 90 ^@ or theta = 180 ^@`
