2008MoZV: ²⁶Mg(¹⁸O,Xγ) E=3.72, 5.0 MeV/nucleon from JAEA tandem; measured Eγ, Iγ, γγ-coin using GEMINI-II Ge detector array; deduced levels, J, π. In this short report, the authors mention that a level scheme of ³⁸Cl up to 4836 level is deduced based on their results; but no details are given. The following γ rays are from Fig.1 of a coincidence spectrum gated by 171γ+292γ+1191γ: 554, 638, 755, 1021, 1030, 2044, 2681.
