We use the hyperspherical coordinates to describe decay of many‐body resonances. Direct and sequential decay are described by different paths in the distances between the particles. We generalize the WKB expression for the α‐decay width to decay of three charged particles. Decay mechanisms and resonance structures are computed in coordinate space. The energy distributions of the particles after decay are discussed. Moderate s‐wave scattering lengths prefer decay via corresponding virtual state possibly leaving unique fingerprints of this reminiscence of the Efimov effect in the decay of excited states. Numerical illustrations are resonances in 6He, 12C, 17Ne.
