Question

TuteeHUB · Accepted Answer

E_o(M₂+M₁)/(M₂-M₁)

TuteeHUB · Answer

Eo(M2-M1)/(M2+M1)

TuteeHUB · Answer

Eo(M2+M1)/(M2-M1)

TuteeHUB · Answer

Eo(M2‚Äö√†√∂‚àö‚â•M1)/(M2+M1)

TuteeHUB · Answer

Eo(M2-M1)/(M2‚Äö√†√∂‚àö‚â•M1)

1.	Which of the following is the energy after collision with a surface atom for a scattering angle of 90^o when E_o is the energy of the incident ion, M₁ is the mass of the incident ion and M₂ is the mass of the target surface?
A.	E<sub>o</sub>(M<sub>2</sub>-M<sub>1</sub>)/(M<sub>2</sub>+M<sub>1</sub>)
B.	E<sub>o</sub>(M<sub>2</sub>+M<sub>1</sub>)/(M<sub>2</sub>-M<sub>1</sub>)
C.	E<sub>o</sub>(M<sub>2</sub>‚Äö√†√∂‚àö‚â•M<sub>1</sub>)/(M<sub>2</sub>+M<sub>1</sub>)
D.	E<sub>o</sub>(M<sub>2</sub>-M<sub>1</sub>)/(M<sub>2</sub>‚Äö√†√∂‚àö‚â•M<sub>1</sub>)
Answer» B. E<sub>o</sub>(M<sub>2</sub>+M<sub>1</sub>)/(M<sub>2</sub>-M<sub>1</sub>)
