| Abstract: | The lifetime and the -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 state is also reported. Received: 7 March 2000 / Accepted: 12 May 2000 |
