I try to integrate this integral. But I could not. Where is my a mistake? epsk = k^2/2/m Ek = Sqrt[epsk*(epsk + 2*Delta)] sigma0 = -Delta/4/Pi^2*Integrate[k^2/Ek, {k, 0, Infinity}] How can I solve this problem? (The...
Thank you for your answer. It will be helpful for me. I try to simplify the integral, previously. Thank you.
Thank you a lot. It succesfully work.
