General Comments:

1989Gu03: New isotope 29F was produced and identified from the Ta(48Ca,X) reaction, E=55 MeV/u.

2000Oz01: Measured 29F production cross-sections: σf=0.027 nb 14 from 40Ar fragmentation, E=1.06 GeV/u, on Be target.

1999Re16,2001Pe14,1997Ta22: 29F was produced from fragmentation of 2.8 GeV 36S beam on a Ta target; separated in-flight using LISE spectrometer at GANIL and identified through time-of-flight and energy loss measurements. Measured β-delayed γ-rays, β-γ coincidence, and half-life.

1999Dl01: Fragmentation of 36S beam, E-75 MeV/u, on natural C and 181Ta targets; isotopes separated in-flight using LISE spectrometer at GANIL and identified through time-of-flight and energy loss measurements. Measured yields of different isotope production, also measured β- delayed γ-rays and half-life. Second experiment was also performed at JNIR, Dubna: 32S and 34S beams, 6<E<20 MeV/u, on natural C and 197Au targets, the yields of various isotopes were measured using the MSP-144 magnetic spectrometer with a position- sensitive ionization chamber.

1998NoZZ: 29F was produced from the projectile-like fragmentation of a 95 MeV/u 40Ar beam on a 181Ta target; fragments were identified by time-of-flight and energy loss measurements, two plastic scintillation counters, two surface barrier Si detectors, and three Si(Li) detectors, half-life was measured from β- decay measurements.

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔQ(β-)=586(syst), ΔS(n)=766(syst), ΔS(p)=906(syst), ΔQ(α)=766(syst) 2011AuZZ

Q-value: 2003Au03: Q(β-)=22200 600(syst), S(n)=1000 800(syst), S(p)=20800 800(syst), Q(α)=-18600 800(syst)
