Eu isotope produced from p-induced fission of 238U, followed by on-line isotope separation. Assignment to Eu based on observation of Gd K x-rays in the mass-163 fraction.
2007Ha57 (also 2006SaZS): source prepared by 238U(p,F) at E(p)=32 MeV at JAEA facility. Fission products were ionized and separated online using Tokai-ISOL mass separator. Measured Q(β-) using total absorption gamma-ray spectrometer of BGO detector. Deduced mass excess=-56740 100 (2007Ha57), value includes systematic predictions of 2003Au03. Other: mass excess=-56630 500 (syst,2009AuZZ,2003Au03)
Q-value: Note: Current evaluation has used the following Q record $ 4690 70 6050 syst 9160 syst -2200 syst 2009AuZZ,2007Ha57
Q-value: S(n),S(p),Q(α): from 2009AuZZ, 2003Au03. The uncertainties, also from systematics, for these quantities are: for S(n), 590; for S(p), 710; and, for Q(α), 540 (2009AuZZ,2003Au03).
