1977Bu11: identification and production of 34Al isotope in U(p,X) at 800 MeV, spallation reaction, time-of-flight and energy loss measurements, LAMPF facility
1979We10: production of 34Al in fragmentation of 48Ca beam with Be target at 212 MeV/nucleon at Berkeley Bevalac facility.
Later productions and half-life measurements: 1986Vi09, 1986Du07, 1987Gi05, 1988Mu08, 1989Ba50, 1991Zh24, 1991Or01, 1997Fo01, 2005Ob04, 2007No13
2001Nu01 (also 2002Nu02): mass-separated 34Al produced in U(p,X) E=1 GeV reaction using uranium carbide target, CERN-ISOLDE facility. Measured Eγ, Iγ, β, βγ, βγγ, βnγ coin, βγ(t), T1/2 and delayed neutron-emission probability using Ge and BaF2 detectors for γ rays, plastic scintillation detectors for β rays and neutrons.
2006Kh08: Cross section and strong absorption radius measurement in Si(34Al,X) reaction at 44.4 MeV/nucleon and 50.9 MeV/nucleon.
2008Hi01: 9Be(36S,xγ) E=77.5 MeV/nucleon. Extracted 34Al beam using LISE fragment separator at GANIL facility. Beam implanted in Si crystal. Measured magnetic moment using nuclear magnetic resonance (NMR) method following β decay.
2006FuZX: In He(34Al,x) E=40 MeV/nucleon reaction, possible prompt γ rays of 383.7 keV 12 and 425.3 keV 11 are identified, but no level scheme is proposed. The 34Al beam was produced by fragmentation of 63 MeV/nucleon 40Ar beam with carbon+Be target at riken facility using rips separator and grape γ detector array.
2012No05: 9Be(34Al,33Al) at ≈900 MeV/nucleon, GSI facility, one-neutron removal reaction. Measured momentum distribution. Deduced single-particle occupancies in g.s. of 34Al. Eikonal analysis
Mass measurements: 2007Ju03 (cyclotron based mass spectrometry), 1987VaZS
