## Homework Statement

The question is attached below

## Homework Equations

$$P_{i \to n}(t)=\frac{|4H_{ni}|^2}{|E_{n}-E_{i}|^2}\sin^2\bigg[ \frac{(E_n-E_i)t}{2\hbar} \bigg]$$

## The Attempt at a Solution

for simplicity I kept k=1

I don't know whether my approach is correct. That is I am not sure whether I used the correct formula for calculating transition probabilities, I afraid that I have not used the fact the perturbation is turned on at $$t=t_i$$ and turned off at $$t=t_f$$ anywhere in the solution. Any help is appreciated.
