Gaussian functions are a common statistical tool, but they can also be useful in physics and engineering, because they are easy to work with mathematically. In particular, they can also be used to mathematically describe atomic orbitals. Consider an "atom" whose ground state has the form (r)=Aer2/2a2, where a =0.18A and A is the normalization constant. (Note that r is a vector!) What is the value of the normalization constant A ? Your solution: A23. Correct answer The correct answer is A5.549A23
