General Comments:

First identification of 38Cl nuclide was reported by Kenney and Seaborg in Phys Rev 57, 843 (1940), according to the 2012Th10 compilation of isotope discoveries.

Other reactions:

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.

Q-value: S(2n)=16418.70 10, S(2p)=24125 13 (2017Wa10)
