Other measurements:
1999WiZX: 44Cl produced by fragmentation of 48Ca beam at 70 MeV/nucleon with a Be target. Measured Eγ, Iγ, γγ coin and βγγ coin using Ge and Si detectors.
1999Ai02: 44Cl beam from 55Mn fragmentation, Si(44Cl,X) studied. Measured cross section and strong absorption radius. A1200 separator at NSCL facility
2006Kh08: 44Cl beam from 48Ca fragmentation at 60.3 MeV/nucleon with 181Ta target using LISE3 at GANIL facility, Si(44Cl,X) studied. Measured cross section and strong absorption radius
2010De11: measurement of g factor of 44Cl g.s. by β-NMR method. 44Cl produced in fragmentation of 48Ca beam at 60 MeV/nucleon bombarding 9Be target. Secondary beam selected by LISE separator at GANIL facility. Large scale shell-model calculations
Mass measurements: 2018Mi08, 2000Sa21 (also 2001Sa72), 1991Zh24, 1990Tu01
No information is available for population of levels in 44Cl from β- decay of 44S.
The delayed-neutron decay of 45S is reported as 54% (1995So03) which is expected to populate 44Cl, but no level or feeding data are available.
2010Ga15: theory: calculated levels, Jπ using shell model
Theoretical calculations: in addition to one structure reference listed above, four other references for structure and one for radioactive decays retrieved from the NSR database (www.nndc.bnl.gov/nsr/) are listed in document records which can be accessed via web-based ENSDF database
Gammas: Two strong γ rays at 515 and 720 keV are reported by 2009Ri04 in the 9Be(45Cl,44Clγ) reaction, but not placed in the level scheme
