Hi all, since scattering amplitude is given as:(adsbygoogle = window.adsbygoogle || []).push({});

f(theta) = summation over l(from o to infinity)(2l+1)/k exp(i(phi))sin(phi) P_{l}(cos theta).But what happen if i want to calculate the ratio of f(theta=0)/f(theta = pi/2).

Can any one tell me the value of P_{l}(0).

Thanks
