Abstract
Bound state in continuum (BIC) might appear in open quantum dots
for variation of the dot's shape. By means of the equations of
motion of Green functions we investigate effect of strong intradot
Coulomb interactions on that phenomenon in the framework of
impurity Anderson model. Equation that imaginary part of poles of
the Green function equals to zero gives condition for BICs. As a
result we show that Coulomb interactions replicate the
single-electron BICs into two-electron ones.
