I calculated the integral, however i anchieved a "weird" result. I think it was wrong, i expected an exp term. Here my result: \phi\left(p_{x}\right)=-\left(4\Pi h \Delta x\right)^{-\frac{1}{2}}\left[\frac{1}{\frac{ip}{h}+\frac{1}{2\Delta x}}+\frac{1}{\frac{ip}{h}- \frac{1}{2\Delta x}}...

Homework Statement Consider the wave packet \psi\left(x\right)=\Psi\left(x,t=0\right) given by \psi=Ce^{\frac{ip_{0}x}{h}-\frac{\left|x\right|}{2\Delta x} where C is a normalization constant: (a) Normalize \psi\left(x\right) to unity (b) Obtain the corresponding momentum space wave...

I cannot deal with arctg z in the argument of sec ( ). Its necessary to my purpose find a solution without arctg or sec ( ). However Mute's suggestion would be usefull, i ll try this one and made another attempt.

Sorry, i made a typing mistake here, the integral is: \int u/ \left(R^{2}+r^{2}+2Rru\right)^{1/2} du

Another one: \int u/ \left(R^{2}+r^{2}+2Rru\right)^{1/2} du
