Question: (a) Verify by explicit integration that the integral is left unchanged by the substitution (B.47a) in the limit that Î/E 0 0 at fixed E

(a) Verify by explicit integration that the integral

I (E – Eo)² +T² /4

is left unchanged by the substitution (B.47a) in the limit that Γ/E0 †’ 0 at fixed E0.

(b) Show that (B.47a) and (B47b) are compatible close to the resonance if Γ << E0.

I (E Eo) +T /4
