A.Adahchour, P.Descouvemont

Three-body continuum of ²⁶O

NUCLEAR STRUCTURE ²⁶O; calculated ²⁴O+n+n three-body eigenphases for J=0+, 1- and 2+; deduced narrow resonance for J=2+ near 1.3 MeV with Γ ≈ 0.4 MeV, in agreement with recent experimental data. Hyperspherical formalism for ²⁴O+n and n+n interactions, and R-matrix technique to derive wave functions and associated phase shifts.
