38Ti has not yet been identified.
1996Bl21 used reaction 9Be(58Ni,X) E=650 MeV/nucleon to measure fragment production cross section of 38Ti, but there was no evidence of the presence of this nuclide in their mass spectra. An upper limit of half-life was estimated as <120 ns from estimate of cross section for 38Ti in comparison with production trends for other nuclides such as 58Ni

With S(2p)=-2540 300 (syst,2017Wa10), 38Ti is expected to be unstable to two-proton emission.
