2000Kr18, 1998KaZM: 129Ag produced through spallation of Uranium using 1 GeV p beam at ISOLDE-CERN facility, Laser isotope separator. Measured β-n, proportional counter, observed g.s. decay and a possible isomer.
Structure calculations:
2007Cu03: calculated T1/2, Q(β-)value, G-T strength distributions, S(2n), delayed one-neutron emission probability
2003Mo09: calculated T1/2, discussed astrophysical r-process
2003Bo06: calculated T1/2
2003Br19: calculated level-mixing features, β-decay T1/2
Q-value: Estimated (2012Wa38) uncertainties: 360 for Q(β-), 420 for S(n), 670 for S(p), 590 for Q(α)
Q-value: S(2n)=9770 360, Q(β-n)=6960 300 (syst,2012Wa38). S(2p)=31890 (theory,1997Mo25)
