“…The adjusted (see 141 Cs, above) ISOLTRAP mass excess of −70.521 (15) MeV is in agreement with our result of −70.511 (10) MeV. Again utilizing previous CPT mass measurements [1], we can calculate Q β to be 7.340 (15) MeV, which is 1.2 σ from the value from [65] of 7.315 (15) MeV.…”

“…159 Sm: The AME03 cites a single β-endpoint measurement for this nuclide of Q β = 3.840(100) MeV [49], which has since been reanalyzed by the same group in Hayashi et al [48] resulting in Q β = 3.805 (65) MeV. Both values agree with the CPT value of 3.834 (14) MeV.…”

“…The other two cited measurements are a β-endpoint measurement of Q β = 5.242 (15) MeV [65], and a betadelayed neutron measurement [57]. We can compare with the Q β measurement by using an earlier CPT measurement of 141 Ba [1] to calculate Q β = 5.274 (20) MeV, a difference of 1.3 σ.…”

“…142 Cs: For this nuclide the AME03 considers the ISOLTRAP mass measurement [3] and a Q β measurement [65] with an additional contribution from the Orsay mass spectrometer [64], with which we cannot make a direct comparison. The adjusted (see 141 Cs, above) ISOLTRAP mass excess of −70.521 (15) MeV is in agreement with our result of −70.511 (10) MeV.…”

Mass measurements near ther-process path using the Canadian Penning Trap mass spectrometer

The masses of 40 neutron-rich nuclides from Z = 51 to 64 were measured at an average precision of δm/m = 10 −7 using the Canadian Penning Trap mass spectrometer at Argonne National Laboratory. The measurements, of fission fragments from a 252 Cf spontaneous fission source in a helium gas catcher, approach the predicted path of the astrophysical r process. Where overlap exists, this data set is largely consistent with previous measurements from Penning traps, storage rings, and reaction energetics, but large systematic deviations are apparent in β-endpoint measurements. Differences in mass excess from the 2003 Atomic Mass Evaluation of up to 400 keV are seen, as well as systematic disagreement with various mass models.

“…Since 141 Cs does not decay into the ground state of 141 Ba, the excitation energy (48.5 keV) of the level to which it decays has to be added to the endpoint energy to obtain the Q-value. A recent remeasurement of this decay energy by the same group [31] con rms this result.…”

High-accuracy mass determination of unstable cesium and barium isotopes

et al. 1999

Direct mass measurements of short-lived Cs and Ba isotopes have been performed with the tandem Penning trap mass spectrometer ISOLTRAP installed at the online isotope separator ISOLDE at CERN. Typically, a mass resolving power of 600 000 and an accuracy of m 13 keV have been obtained. The masses of 123;124;126 Ba and 122m Cs were measured for the rst time. A least-squares adjustment has been performed and the experimental masses are compared with theoretical ones, particularly in the frame of a macroscopic-microscopic model.
