General Comments:

1990Tu01, 1994Se12: 56Ti produced in proton-induced fragmentation and fission reactions on natural Thorium using the high-intensity proton beam of the Los Alamos Meson Physics Facility. Measured mass excess of g.s. of 56Ti using Time-of-Flight Isochronous (TOFI) spectrometer.

1996Do23: 56Ti produced and identified in the fragmentation of 64.5 MeV/nucleon 65Cu beam with 90 mg/cm2 9Be target and separation of fragments using LISE3 spectrometer at GANIL. Measured β singles, βγ-coin, and T1/2 of decay of 56Ti

1998Am04 (also 1997AmZZ thesis): 56Ti produced and identified in the fragmentation of 500 MeV/nucleon 86Kr beam with 2 g/cm2 9Be target and separation of fragments using FRS spectrometer at GSI facility. Measured (implants)β-correlations, and T1/2 of decay of 56Ti

2003Ma56: 56Ti isotope produced in 9Be(86Kr34+,X) at E=140 MeV/nucleon, followed by separation of fragments using A1900 fragment separator at NSCL-MSU. Measured Eγ, Iγ, γγ-coin, βγ-coin, T1/2 of 56Ti decay using a double-sided Si microstrip detector (DSSD) and Segmented Germanium Array (SeGA) arranged around the β counting system
