2010Oh02: ⁷¹Mn nuclide identified in Be(²³⁸U,F) and Pb(²³⁸U,F) reactions with a ²³⁸U^86⁺ beam energy of 345 MeV/nucleon produced by the cascade operation of the RIBF-RIKEN accelerator complex of the linear accelerator RILAC and four cyclotrons RRC, fRC, IRC and SRC. Identification of ⁷¹Mn nuclei was made on the basis of magnetic rigidity, time-of-flight and energy loss of the fragments using BigRIPS fragment separator.

Theoretical calculations:

2016Sh39: calculated β^- decay half-life using proton-neutron finite-amplitude method (pn-FAM) with Skyrme energy-density functionals (EDFs)

2014Mi23: calculated β^--delayed-neutron emission probabilities using effective density model.

Q-value: ΔQ(β^-)=640, ΔS(n)=710, ΔS(p)=ΔQ(α)=780 (syst,2021Wa16)

Q-value: S(2n)=7400 640, Q(β^-n)=12200 580 (syst,2021Wa16)

Q-value: Q(β^-2n)=6440 540, Q(β^-3n)=3070 540 (deduced by evaluators from masses in 2021Wa16). S(2p)=17430 (2019Mo01, theory)

Q(β-)=15310 keV SY	S(n)= 4240 keV SY	S(p)= 18270 keV SY	Q(α)= -17300 keV SY
