✦ Synopsis

We appl) the Schwmger method, two Kohn-type methods, and three Hurls-Mlchels-type methods to electron scattertng by the same potential wtth the same sets of basts functtons

We also test a polynomtal basts in the Schwmger method. We use Nesbct and Obcrot's method to avold spurtous stnguhrtttes of the Kohn method Kohn and Hams-Mxhels methods show much better convcrgencc to the accurate result than tbc Schwtnger method
