“…Activities of 146 La were produced by the thermal neutron fission of 235 U, followed by use of the on-line mass separator KUR-ISOL [12] installed at a through-tube facility of the Kyoto University Reactor. As the target, 30 mg of 235 U was irradiated with the thermal neutron flux of 3×10 12 n·cm -2 s -1 .…”

The β-decay of 146 La was studied using the on-line isotope separator KUR-ISOL. Gammagamma angular correlation measurements were performed with a 4-Ge detectors system. Spin assignments of three levels were made: 3 + for the 1576.5 keV level, 4 + for the 1627.1 keV level and 5 + for the 1810.2 keV level. The mixing ratios (E2/M1) were deduced to be δ183.2 = 0.25±0.08, δ638.9 = 0.33±0.05, δ959.0 = 1.19 +0.16 −0.14 , δ1015.9 = 5.4 +3.1 −1.5 and δ1318.1 = 6.5 +1.7 −1.1 . These were compared to the calculated values obtained in three cases involving different Majorana force parameter values. The band structure of 146 Ce is discussed based on the results of calculation using the IBM-2 theory.

“…To eliminate this ambiguity, we plan TDPAC measurement using 140 Ce kinetically implanted as 140 Cs beam from our on-line mass separator (KUR-ISOL) [6]. Now KUR-ISOL is temporarily shut down due to a large modification of KUR and expected to be available again early in 2009.…”

“…For detailed descriptions of KUR-ISOL, see references. [5][6][7] In the present study, 140 Cs was implanted into CaB 6 and 140 La was obtained in the radioactive equilibrium of 140 Ba-140 La, followed by the β decay of 140 Cs. A relevant part of the decay scheme of the A = 140 mass chain is shown in Fig.…”

A 140 La(I π = 3 − , T 1/2 = 40.3 h)-doped layer has been produced in CaB 6 by means of radioactive isotope (RI) beam technique: 140 Cs(I π = 1 − , T 1/2 = 63.7 s) was implanted into CaB 6 and the radioactive equilibrium of 140 Ba-140 La was achieved. The concentration of La in CaB 6 was La/Ca ∼ 0.001 and ∼0.005. Obtained TDPAC spectra of the 2083 keV level of 140 Ce (I π = 4 + , T 1/2 = 3.4 ns, µ = +4.35±0.10µ N ) followed by the β decay of 140 La showed the existence of hyperfine magnetic fields: B hyp = −15.0±0.5 T and −1.00±0.15 T for La/Ca ∼ 0.001 and B hyp = −1.51 ± 0.12 T for La/Ca ∼ 0.005.
