Abstract We report on a measurement of the lifetime of the 1414 keV state in232Th by the Doppler-shift recoil-distance method. This 4+ state shows all characteristics of a nearly-harmonic two-phononγ-vibrational excitation. The result for the B(E2) value obtained from the lifetime,τ=3.2 ± 0.7 ps, is in agreement with an earlier estimate of the collectivity from Coulomb-excitation yields and supports the interpretation of the 1414 keV state as a two-phononγ-vibrational excitation.
