摘要：

We report on a measurement of the lifetime of the 1414 keV stale in Th-232 by the Doppler-shift recoil-distance method. This 4(+) state shows all characteristics of a nearly-harmonic two-phonon gamma-vibrational excitation. The result for the B(E2) value obtained from the lifetime, tau = 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-phonon gamma-vibrational excitation.
