چکیده
|
We studied the alpha-alpha particle scattering (αα) with halo effective field theory (heft) as well as halolike systems. in this paper, we considered α-α elastic scattering in s-wave state at the very low energy. because of the unnaturally large scattering length of a αα, it is considered as a halo system. we defined the la- grangian of this system and then calculated the t-matrix for the scattering amplitude at leading order by using of the feynman diagrams. for the α-α elastic scattering at energy about 0.29 mev, the total cross section that with this approach has been calculated will be σt cong 16:0226 mb.
