The lifetime and the γ-decay to the 0+ ground state of the lowest 3- state in 148Gd has been determined. The reduced strength B(E3, 3- → 0+)=41 (6) W.u. agrees well with the theoretical value from empirical shell model calculations and can be directly compared with the 12+ → 9- two-octupole-phonon → one-octupole-phonon strength obtained in the same Recoil Distance Method lifetime measurement. The results of our search for a three octupole-phonon state built on the (vf7/2)26+ state is also reported.
