✦ Synopsis
The quadrupole moments of the short-lived fl-emitting nuclei 130 (U = 3/2-, T1/2 = 8.6 ms), 190 (U = 5/2 +, Ta/2 = 27 s) and 2aF (U = 5/2 :~, T1/2 = 4.3 s) were determined to be IQ(130)1 = 11.0 + 1.3 rob, IQ(190)1 = 3.7 -l-0.4 mb and IQ(21F)I = 110 4-22 mb by detecting their •-NMR. The present results are compared with the theoretical values obtained by the Hartree Fock calculations taking their one nucleon-separation energies into account.
