General Comments:

2012Ga06: Summary and compilation of the discovery of the Mn isotopes.

2011Da08,2002MaZN (thesis): Produced by projectile fragmentation of 86Kr beam on 50 mg/cm2 thick Ta at 57.8 MeV/nucleon. Separated by LISE2000 spectrometer at GANIL. Detector system included a three-element Si-detector telescope containing a double-sided silicon-strip detector (DSSSD) backed by a Si(Li) detector and surrounded by four clover type EXOGAM Ge detectors. Product identified by mass, atomic number, charge, energy loss and time of flight. Measured isotopic T1/2 from timing correlation between implanted ions and β decay events. Fitting procedure included five parameters: β-detection efficiency, background rate, mother, daughter and granddaughter half-lives.

1999Ha05: Produced by 1 GeV proton-induced spallation of U in a thick UC2 target at the ISOLDE facility at CERN. Identification and T1/2 measurements by chemically selective laser ionization and β- delayed n counting with the Mainz 4π3 He neutron detector.

1997Be70: Produced by projectile fission of 238U on 9Be target at 750 MeV/nucleon. Fission fragments separated with the FRS separator at GSI and identified by combination of ΔE-Bρ-tof, and trajectory. α total of 5 counts were assigned to 69Mn corresponding to cross section of 0.4 nanobarns.

Q-value: ΔQ(β-)=720, ΔS(n)=780, ΔS(p)=920, ΔQ(α)=780 (syst,2012Wa38)

Q-value: Q(β-n)=11220 700 (syst,2011Wa38)
