General Comments:

Other measurements:

2009Ma47: 238U(136Xe,Fγ),E=954 MeV; measured prompt Eγ, and γγ-coin using Clara-Prisma spectrometer at LNL-Legnaro. Detected first three γ rays of 213, 352 and 497 keV in the yrast cascade.

2009Sh42: 12C(238U,100Zrγ),E=1.45 GeV; measured Eγ, (100Zr)γ-coin using VAMOS magnetic spectrometer for fragments at GANIL. Detected first five γ rays of 212, 351, 498, 625, and 739 keV in the yrast cascade.

Mass measurements: 2007Ri01, 2006Ha03, 2006Jo14, 2005Jo22, 2004Ri12, 2004Jo18: Penning-trap method at Jyvaskyla, all the papers are from the same group.

Theory references: consult the NSR database (www.nndc.bnl.gov/nsr/) for 110 primary references, 104 dealing with nuclear structure calculations and six with decay modes and half-lives.

Q-value: S(2n)=11233 12, S(2p)=24532 9 (2017Wa10)

E(level): From least-squares fit to Eγ data, keeping the energy of the first 2+ level fixed at 212.61 4, and assuming Δ(Eγ)=0.3 keV when not stated

Jπ(level): For high-spin (J>5) states, the assignments are essentially based on yrast type of population in high-spin studies (from SF decay studies) where ascending order of spins are expected as the excitation energy increases complemented by band associations.

M(γ): From ce data in 100Y β- decay (732 ms), unless otherwise noted.
