Phys. Rev. C 41, 937–941 (1990)Particle stability of the isotopes 26O and 32Ne in the reaction 44 MeV/nucleon 48Ca+TaReceived 31 October 1989; published in the issue dated March 1990 An attempt has been made to synthesize the extremely neutron-rich isotope 26O in the nuclear reaction 44 MeV/nucleon 48Ca+n/rTa. Use was made of magnetic separation and identification methods including time-of-flight and ΔE,E measurements. The 26O nucleus appears to be unstable against particle emission since no events attributable to the 26O nucleus were observed at a level one order of magnitude lower than that predicted from the extrapolated yields. The previously unobserved isotope 32Ne was found to be particle stable and the isotope 31Ne particle unstable. Neutron-separation energies calculated with different models are tabulated. © 1990 The American Physical Society URL:
