Studies in e-COL
laboratory located in Physics department at Afyon Kocatepe University, Turkey
are consantrated on the producing experimental data for the solution of many
body problems in collision physics, in addition to the examination of the
kinematic structure of the atomic and molecular systems and assisting the
development of new theoretical models. In this work, cross sections obtained
for various atoms and molecules are presented in details (http://e2e.aku.edu.tr/).
