42SC c 42TI decays mainly (>99%) through B+ decay
42SC c 2015Mo01: {+42}Ti ions were produced from fragmentation of 680
42SC2c MeV/nucleon {+58}Ni beam with 400 mg/cm{+2} {+9}Be target using SIS-18
42SC3c synchrotron at GSI facility. Reaction fragments were separated
42SC4c in-flight using the fragment separator FRS. The identification of
42SC5c nuclei was achieved by measurement of magnetic rigidity and velocity of
42SC6c fragments from time-of-flight method. Separated ions were implanted in
42SC7c one of six double-sided silicon strip detectors (DSSSDs). The |b-decay
42SC8c signals were detected in the same DSSSD. Surrounding the implantation
42SC9c setup was the RISING array of 15 Euroball cluster detectors for |g
42SCAc detection. Measured E|g, I|g, |g|g-coin, |b|g-coin, and |b-decay
42SCBc half-life. Deduced levels, J, |p, |b feedings, log| {Ift} values,
42SCCc Gamow-Teller strengths. 2012Fu02 is an earlier report without any data
42SC c 1969Ga27: {+42}Ti isotope was produced via {+40}Ca({+3}He,n) reaction
42SC2c using {+3}He beam from the 5.5-MV Van de Graaff at Strasbourg.
42SC3c |g-rays were detected with Ge(Li) detectors (FWHM=4 keV at 1.22
42SC4c MeV). Measured E|g, I|g, T{-1/2}. Deduced levels, branchings.
42SC c 1980HoZO: measured G, limit of delayed proton decay
42SC c 2009Ku19: {+42}Ti produced in {+40}Ca({+3}He,n|g) E=17 MeV, beam
42SC2c from the Ion Guide Isotope Separator On-Line (IGISOL) facility at the
42SC3c Accelerator Laboratory of the University of Jyvaskyla. Target of a
42SC4c 1.5 mg/cm{+2} natural Ca. Measured E|g, |b|g-coin, T{-1/2}, mass
42SC5c differences using JYFLTRAP Penning-trap spectrometer. Measured
42SC6c Q(|e)=7016.83 keV {I25}
42SC c 2015Ha07: review of superallowed decays; evaluated Q value, T{-1/2}
42SC2c branching ratios, {Ift} value, isospin-symmetry-breaking corrections

42SC c A 2222 {I2} (I|g=1.2 {I4}) |g reported by 1969Ga27 is omitted
42SC2c here since it is assigned (by 1980HoZO) to {+1}H(n,|g) line related to
42SC3c background. Thus the 2222 level proposed by 1969Ga27 is also omitted
