General Comments:

1996To08: 144Sm(40Ca,4n), E=230 MeV. Measured Eα, Iα; deduced evidence for 180Pb

1999To11: 90Zr(92Mo,2n), E=410 MeV. Measured Eα, T1/2; deduced α-branching ratio.

2009An20: 144Sm(40Ca,4n), E=196 MeV. Measured Eα, (recoil)α, αα correlations, T1/2, α-branching ratios.

Q-value: Q(εp)=7710 30; S(2n)=21641 28; S(2p)=191 18 (2012Wa38)
