General Comments:

First identification of 40P nuclide by 1979Au03.

Mass measurement: 2007Ju03, 2001Sa21 (also 2001Sa72), 1991Zh24

2003Gr22: 40P produced by fragmentation of 48Ca beam at 60 MeV/ nucleon with a 9Be target followed by separation of fragments by LISE3 spectrometer; measured β, γ, T1/2. See also 2004Gr28, 2004Gr20.

2001Wi21: 40P was produced in the fragmentation of 48Ca beam at E=70 MeV/nucleon with a Be target followed by analysis using using A1200 fragment separator.


1989Le16: 40P formed and identified in 181Ta(48Ca,X). Measured T1/2 and %β-n

1979We10: 40P produced in 9Be(48Ca,X) at 212 MeV/nucleon

1979Au03: 40P produced in 238U(Ar,X) at 263 MeV. Measured fractional-charge parameter versus α. Deduced evidence for 37Si, 40P, 41,42S.

1999YoZW, in a preliminary result, suggested that 41Si decays dominantly (>50%) by β-n decay to 40P, but final details of this study are not yet available

Q-value: S(2n)=9550 140, S(2p)=38860 270, Q(β-n)=7020 120 (2012Wa38)
