General Comments:

No new experimental references since the last ENSDF update in 2013, except the 2015Lo04 which is included here

1994Be24: produced by Pb(238U,F), E=750 MeV/nucleon at GSI; identification by time-of-flight. See also 1998Do08 from the same lab

1997So07: 116Ru produced in 208Pb(238U,X) at 20 MeV/nucleon

2006Mo07: 116Ru produced in fragmentation of 136Xe at 121.8 MeV/nucleon with 9Be target. The A1900 fragment separator at NSCL facility at MSU was used to separate nuclei of interest. The secondary beam was implanted into β-decay arrangement consisting of Si(PIN) detectors and Si strip detectors (DSSD) and single-sided Si strip detectors (SSSD). Implantation and decay events were time stamped and correlated. Measured half-life from β spectrum

2011Ha48: measured precise mass by Penning-trap method at JYFL.

2015Lo04: measured half-life from ion-β correlations, isotope produced in 9Be(238U,F) reaction at E=345 MeV/nucleon at RIKEN facility

Nuclear structure calculations:

2010Bo12 (also 1980Va15), 2010No01, 1998Du02: levels, J, π, B(E2), potential energy surfaces; IBM-1 model.

1997Sk01: ground state deformation and other spectroscopic properties

Levels: Bands are proposed by 2013So17 based on IBM-1 model calculations

Q-value: Estimated uncertainties: ΔS(p)=ΔQ(α)=200 (2012Wa38)

Q-value: S(2n)=9990 5, S(2p)=28840 300 (syst), Q(β-n)=2089 8 (2012Wa38)
