Hi, so I'm having a bit of trouble understanding the normalization of radial waves. I understand that the equation is the integral of ((R^2)r^2)=1 but I'm not understanding how the process works. I need the normalization constant on R32. I got the function to come out to be (((r^2)(Co)(e^(-r/3a))/(27a^3)) so I can take that and plug it into the normalization equation (with r/a=z) to get ((Co)/(27a^3)^2) (a^4) integral of (z^2)(e^(-z))(z^2)dz then I combined both the z^2's so it's now the stuff out front integral of ((z^4)(e^(-z))dz and this is where I'm stuck. From what I keep seeing is that people are getting actual numerical values and I don't understand how that part works. Please help.
