General Comments:

Identification and production of 42I(γ+ce) nuclide by 1962Ob03 using 40Ca(3He,n) which measured a half-life of 0.25 s 4

2009Ku19: 42Ti produced in 40Ca(3He,nγ) E=17 MeV, beam from the Ion Guide Isotope Separator On-Line (IGISOL) facility at the Accelerator Laboratory of the University of Jyvaskyla. Target of a 1.5 mg/cm2 natural Ca. Measured Eγ, βγ-coin, T1/2, mass differences using JYFLTRAP Penning-trap spectrometer.

Q-value: Estimated uncertainty for Q(β-)=300 (syst,2012Wa38)

Q-value: S(2n)=32400 160, S(2p)=4836.20 28, Q(εp)=2744.25 24 (2012Wa38)
