    "abstract": "We investigate the effect of monopole and quadrupole modes on the elastic\nalpha-alpha resonance structure of $^{8}$Be. To this end we make a fully\nmicroscopic coupled channels calculation with three coupled channels, using the\nAlgebraic Model. The continuum spectrum and wave functions are analyzed in\nterms of the individual channels to understand the nature of the resonances. It\nis shown that both monopole and quadrupole modes have a non-negligible effect\non the resonances in the alpha-alpha continuum.",
