Since I can get the Alm and Blm of the Wave function :ψ can be written as the sum of [Alm*ul(r)+Blm*ul'(r)]Ylm. Here is the question, if I use Alm only to calculate <ψ|σ|ψ>, can I get the close answer? Or can anyone tell me the margin of error of using Alm only compared with using Alm and Blm toghther.<br></div></div></div>
