Abstract

The quadrupole moments of the short-lived β-emitting nuclei 13O (Iπ = 5/2+, T1/2 = 8.6 ms), 19O (Iπ = 5/2+, T1/2 = 27 s) and 21F (Iπ = 5/2+, T1/2 = 4.3 s) were determined to be |Q(13O)| = 11.0 ± 1.3 mb, |Q(19O)| = 3.7 ± 0.4 mb and |Q(21F)| = 110 ± 22 mb by detecting their β-NMR. The present results are compared with the theoretical values obtained by the Hartree Fock calculations taking their one nucleon-separation energies into account.
