| 593 | (2+) | T=1 Jπ(level): Proximity of 595γ and 850γ with Eγ of yrast 2+ to 0+ and yrast 4+ to 2+, respectively, in 86Mo suggests (2000Ch07) possible analogs of yrast 2+ and 4+ (t=0) states in 86Mo. Similar pattern is observed in n=Z nuclides: 62Ga, 66As and 74Rb. | |

1992Ye04: 86Tc identified by in 58Ni(92Mo,X) E=70 MeV/nucleon reaction followed by measurement of fragment mass and charge using A1200 beam analysis device, tof=150 ns.
2001Ga24, 1998Lo17 (also 1999Lo07): 86Tc produced in Ni(92Mo,X) E=60 MeV/nucleon. Measured T1/2
2001Ki13, 2002Fa13: 86Tc produced in 9Be(112Sn,X) E=1 GeV/nucleon. The fragments were separated in FRS (fragment-recoil separator) and identified by measuring energy loss and time-of-flight. Measured T1/2
Q-value: ΔS(n)=500, ΔS(p)=300, ΔQ(α)=420 (syst,2012Wa38)
Q-value: S(2p)=4860 420, Q(εp)=7690 300 (syst,2012Wa38). S(2n)=28220 (calculated,1997Mo25)
