(Note: This problem has been edited from its original version, to correct an obvious error in the units of measurement and the normalization of the wavefunction that made it unsolvable.)

We are given this wavefunction:

`psi(r) = 1/sqrt(alpha_0 sqrt(pi)) e^{-r/alpha_0}`

The probability density of finding the atom at a given point is given by the absolute square of the wavefunction at that point:

`p(r) = abs(psi(r))^2 = 1/(sqrt(pi) alpha_0) e^{-r^2/alpha_0^2}`

Normally, to get the overall probability...
