摘要：
Following the identification of the lowest-spin member of the two-phonon octupole quartet in Pb-208, the additional members of the multiplet have been sought with the (n,n' gamma) reaction. Based on energy arguments and E1 transition probabilities determined from Doppler-shift lifetime measurements, the 5286- and 5216-keV states are suggested as candidates for the 2(+) and 4(+) two-phonon octupole excitations in Pb-208. The difficulties of identifying the 6(+) member of this quartet are examined. [S0556-2813(98)50205-1].
