38P first produced and identified by 1971Ar32 in 232Th(40Ar,X) at E=290 MeV.
1986Du07 produced 38P in 9Be(40Ar,X) E=60 MeV/nucleon, measured half-life and βγ coin, deduced decay scheme of 38P to 38S
Other measurements:
1987Gi05: 181Ta(40Ar,X) E=60 MeV/nucleon, measured fragment rigidity, deduced mass excess
1991Zh24: 232Th(p,X) E=800 MeV
1997Fo01: 208Pb(37Cl,X) E=230 MeV, measured yield of 38P
1995ReZZ: 232Th(p,X) E=800 MeV. Measured β(fragment) coin, %β-n
1999Ai02: 9Be(55Mn,X) E=90 MeV/nucleon, deduced integrated cross section and strong absorption radius
2006Kh08: Cross section measurement in Si(38P,X) E=30-65 MeV/nucleon, deduced reduced strong absorption radius=1.210 fm2 24. The 38P beam obtained from fragmentation of 48Ca beam with 181Ta target at GANIL facility.
