Homework Statement
Suppose that a hydrogen atom is in the 2s state. Taking r = a0, calculate value for [tex]\psi[/tex]2s(a0)
Homework Equations
I did spherical harmonics for l=0 ml=0 times the radial wavefunction for n=2 l=0. Got the same thing as the solution manual attached but when I started calculating I did not get the same final answer. I would just like someone else to punch in the numbers and see if they get the final answer in the book or perhaps something different, like I did.
The Attempt at a Solution
My final answer turned out to be 1.57*10^14 m^(3/2)
My main question is how the author got e^(1/2) over 4(2pi)^(1/2) = 0.380, see underlined terms in pic (latex is not working for me today)
