AbstractAbstract
[en] The Coulomb excitation of the 67Zn nucleus levels with energies of 184.6(3/2-); 393.6 (3/2); 815.2 (7/2-); 870.9 (3/2-, 5/2-, 7/2-) and 888.0(5/2-) has been restudied. The thick target enriched with the 67Zn isotope to 30.9% was bombarded with alpha particles and 14C, 14N and 16O ions with the energies of 7.5, 30, 35 and 39 MeV respectively. The direct gamma spectra were detected. Excitation of all the levels, except the 870.9 keV one, was observed. The absence of the 870.9 keV lines in the experimental spectra permitted to estimate only the upper boundary of the B(E2) proceeding from background fluctuations at this energy of gamma radiation. The estimate resulted in the B(E2)sub(0 → 871) value which is 130 times below the figures reported by other authors. The results of the 67Zn nucleus coulomb excitation and comparison with the Alagi model calculations are presented in the table. The B(E2) values for transitions from the ground state to 184.6, 815.2 and 888 keV levels are consistent with the results of other investigations; the B(E2) value for 393.6 keV however differs from the earlier observed ones
