First identification of 39Al nuclide by 1989Gu03 in 181Ta(48Ca,X) reaction.
Measurements with 181Ta(48Ca,X) reaction:
1989Gu03: E=55 MeV/nucleon 48Ca beam was produced at GANIL; measured fragment spectra.
2007Ju03: E=60.3 MeV/nucleon 48Ca beam at GANIL; measured mass excess by time-of-flight technique. Measured mass excess=20170 keV 630 as compared to 20650 400 (syst) in 2017Wa10.
Measurements with 9Be(48Ca,X) reaction:
2004Gr20 (also 2003Gr22): E=60 MeV/nucleon 48Ca beam at GANIL; measured β, γ, T1/2 using Si and Ge detectors.
2000Sa21 (also 2001Sa72): E=60 MeV/nucleon; measured mass.
1999YoZW: also 181Ta(48Ca,X) E=70 MeV/nucleon; measured T1/2 and β-n. Results are tentative according to an email reply from the authors
