A neutron collies head-on with a stationary hydrogen atom in ground state. Which of the following statements is/are correct ?

A

If kinetic enerfy of the neutron is less than `20.4 eV` collision must be elastic

B

If kinetic enerfy of the neutron is less than `20.4 eV` collision must be inelastic

C

Inelastic collision may be take place only when initial kinetic energy iof neutron is greater than `20.4 eV`

D

Perfectly inelcastic collision can not take place

Text Solution

Verified by Experts

The correct Answer is:
A, C
`K ge 20.4 eV` for inelastic collision
