First determination of β-delayed multiple neutron emission beyond A-100 through direct neutron measurement: The P_2n value of ¹³⁶Sb

RADIOACTIVITY ¹³⁶Sb(β^-), (β^-n), (β^-2n), ¹³⁶Te(β^-), (β^-n)[from U(p, F), E=25 MeV]; measured Eβ^-, Iβ^-, E(n), I(n), β^- and neutron time correlated events, %β^-n (or P_1n) for decays of ¹³⁶Sb and ¹³⁶Te, and %β^-2n (or P_2n) for decay of ¹³⁶Sb using JYFLTRAP Penning trap for isotope separation, plastic scintillator for β detection, and BELEN array of ³He counter tubes for neutron detection at the University of Jyvaskyla accelerator facility. Comparison with previous experimental values, evaluated data, and with several theoretical predictions.
