General Comments:

1989Le16: 44S identified in 181Ta(48Ca,X) reaction. Measured isotopic half-life

1993So06 (also 1995So03): 44S identified in 64Ni(48Ca,X) E=60 MeV/nucleon using LISE fragment spectrometer at GANIL facility, measured isotopic half-life and decay modes.

2006Kh08: measured energy-integrated reaction cross section.

2010Mo12: analyzed effects of the tensor force on the neutron and proton gaps.

Mass measurements: 2009Ri12, 2007Ju03, 2000Sa21 (also 2001Sa72)

Mean-square radius from energy-integrated cross sections: 2006Kh08

Structure calculations (levels, B(E2), etc.): 2004Ca34, 2002Ca48

Q-value: Note: Current evaluation has used the following Q record

Q-value: Q(β-n)=7240 250, S(2n)=7565 187, S(2p)=40240 520 (syst) (2011AuZZ)

Q-value: Values in 2003Au03: Q(β-)=11110 410, S(n)=5220 440, S(p)=22170 1050, Q(α)=-17010 680, Q(β-n)=6980 420, S(2n)=7580 410, S(2p)=42130 640 (syst)

Q-value: Other: Q(β-)=11130 178 from measured mass excess(44S)=-9100 140. (2007Ju03) and mass excess(44Cl)=-20230 110 (2003Au03). Q(β-n)=6949 191 (deduced from measured masses in 2007Ju03).
