Mass measurements: 2012Na15 (M.E.=-40967.3 37), 2011Es06 (M.E.=-40790 31), 1994Se12 (M.E.=-40900 600)
2012Na15: 65Mn was produced via U(p,X) with 1.4 GeV proton beam from CERN’s Proton Synchroron Booster (PSB) on a UCx target. Fragments were separated and transported through the General Purpose Separator (GPS) and sent to the ISOLTRAP. Measured radio frequency. Deduced mass excess
2011Es06: 65Mn was produced by fragmentation of a 100 MeV/nucleon 86Kr beam on a Be target at NSCL. Fragments were separated by the A1900 separator and analyzed with the S800 magnetic spectrograph. Measured time-of-flight. Deduced mass excess using the tof-Bρ method
1994Se12: 65Mn was produced va natTh(p,X) with 800 MeV proton beam from the Los Alamos Meson Physics Facility (LAMPF). Measured time-of-flight with the TOFI spectrometer. Deduced mass excess.
2011Da08: 65Mn was produced in the fragmentation of 57.8 MeV/nucleon 86Kr beam impinged on 50 mg/cm2 thick tantalum target at GANIL. Fragments were identified and selected using the LISE-2000 spectrometer with a three-element Si-detector telescope, and implanted into a double-sided silicon-strip detector (DSSSD) backed by a Si(Li) detector and surrounded by four clover type EXOGAM Ge detectors. Measured implant-β time correlation. Deduced 65Mn decay half-life. See also 2002MaZN thesis
2003So21: 65Mn was produced by fragmentation of a 61.8 MeV/nucleon 76Ge beam on a 58Ni target at GANIL. Fragments were identified and seperated by the LISE3 spectrometer with 3 consecutive silicon detectors, and implanted into the last Si detector surrounded by 4 Ge detectors for γ detection. Measured Eβ, βγ-coin, implant-β(t). Deduced 65Mn decay T1/2. See also 1999So20, 1999Le67, 2005Ga01 of the same group and 2005GaZR thesis.
2013Ol06: mass separated 65Mn was produced at ISOLDE in CERN. Measured β particles with a plastic scintillator and γ rays with two LaBr3(Ge) detectors. Measured Eβ, Iβ, Eγ, Iγ, βγ(t). Deduced β-delayed neutron emission probability for 65Mn decay, 65Mn T1/2.
1999Ha05: 65Mn was produced via UC2(p,X) with 1 GeV proton from the ISOLDE facility at CERN. Measured Eγ, E(n), Eβ, βn(t). Deduced 65Mn T1/2
1998Am04: 65Mn was produced via fragmentation of a 500 MeV/nucleon 86Kr beam on a Be target at GSI. Measured implant-β time correlation. Deduced 65Mn T1/2
1985Gu14: 65Mn produced by fragmentation of 33-MeV/u 86Kr beam incident on thick Ti and Ta targets and identified through time-of-flight and ΔE-E measurements with a resolution of ΔZ/Z<1.5% and ΔA/A<1%
