General Comments:

Mass measurement: 2007Ju03

1989Gu03: 44P first identified in 181Ta(48Ca,X) E=55 MeV/nucleon reaction followed by measurement of fragment spectra

2004Gr20, 2003Gr22: Fragmentation of 48Ca beam at 60 MeV/nucleon with Be target. The fragments were separated using LISE3 spectrometer at GANIL facility. The fragment identification by energy loss and time-of-flight measurements using Si detectors. Measured γ, ce using a Si(Li) detector and two Ge clover detectors.

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

Q-value: Estimated uncertainties (2011AuZZ): 810 in Q(β-), 880 in S(n), 1130 in S(p), 1060 in Q(α)

Q-value: Q(β-n)=14440 810, S(2n)=6710 830, S(2p)=45590 1210 (syst,2011AuZZ)

Q-value: Values from syst in 2003Au03: Q(β-)=21220 800, S(n)=1740 1190, S(p)=21890 990, Q(α)=-19620 990, Q(β-n)=15990 730, S(2n)=4980 830, S(2p)=46160 1140

Q-value: Other: Q(β-)=18480 911 from measured mass excess(44P)=9380 900 (2007Ju03) and measured mass excess(44S)=-9100 140 (2007Ju03). Q(β-n)=13379 906 (2007Ju03, deduced from measured mass excesses)
