Reference: 2012WA38

General Comments:

2014De41:69Kr isotope produced in the fragmentation of 70 MeV/nucleon 78Kr beam with Be target at the NSCL. Fragments selected with the A1900 separator and purified. Measured T1/2 of 69Kr from β+ decay correlation time spectrum.

2014Ro14, 2011Ro47: 69Kr produced from fragmentation 78Kr on natural Ni target and mass selected by α-LISE3 at GANIL. tof, ΔE and decay spectroscopy of implanted fragments on DSSD correlated with β delayed protons were performed. Deduced T1/2 of 69Kr from β+ decay correlation time spectrum.

1997Xu01: 69Kr produced by 40Ca(32S,3n) reaction using a E(32S)=170 MeV beam incident on a natural calcium target Measured T1/2 and delayed proton emission by pulsed-beam technique and ΔE-E telescope and Si(Au) surface barrier detectors

1995Bl06: 69Kr identified by projectile fragmentation of 73 MeV/u 78Kr beam incident on a Ni target followed by the time-of-flight and ΔE-E measurements at GANIL. The identification was confirmed by measuring γ-rays of known isomers.

Q-value: ΔS(p)=510, ΔQ(α)=720 (syst,2012Wa38)
