  The photoassociation of Efimov trimer, composed of three identical bosons, is
studied utilizing the multipole expansion. For identical particles the leading
contribution comes from the r^2 s-mode operator and from the quadrupole d-mode
operator. Log-periodic oscillations are found in the photoassociation response
function, both near the energy threshold for the leading s-wave reaction, and
in the high frequency tail for all partial waves.
