“…These authors proposed a decay scheme with 26y-transitions, deexciting 14 different levels with energies between 22 keV and 880 keV. Also, the half-life of this isotope has been reported in [13], where a value of T~/2= 22.4 +_ 1.5 s is given. The /~-decay of t51Pr has been investigated in the present study at the LOHENGRIN separator of the ILL, using a target of 1 mg 239pu.…”

The fl-decay energy of the neutron-rich isotopes 148Ba, 14SLa and ~5~pr has been measured at the Institute Laue-Langevin (ILL). The t4aBa-and ~48La-nuclei were produced using a high-temperature ion source at the OSTIS separator of this institute, whereas samples of ~51pr were obtained from the thermal fission of 239pu, used as a target in the mass separator LOHENGRIN. At both instruments, fiT-coincidences were measured with a plastic scintillator telescope and a Ge(I)-detector, together with//-singles and 7-singles spectra. The//-spectra emitted in coincidence with 44~)-lines in the decay of these nuclei have been evaluated. From their endpoint energies, the following Qa-values have been obtained: Qa(lgSBa) = 5115_ 60 keV; Qp(14SLa) = 7255_ 55 keV; Qp(~5 tPr)= 4170 +_ 75 keV. Using these results, the nuclear masses A of these nuclei can be calculated with a relative error AA/A~-5.10 -7. In addition, the two-neutron separation energies and the mass excesses have been derived; the results are compared with recent predictions of theoretical mass calculations.
