2012Zh06: Production cross sections |J1.1 mb and |J1.5 mb were measured in fragmentation of 9Be(40Ar,X) and 181Ta(40Ar,X), E=57 MeV/nucleon, respectively.
2007No13: 30Al production cross section |J3 mb and |J8 mb were measured in 40Ar fragmentation reactions of 9Be(40Ar,X), E=90α MeV, and 181Ta(40Ar,X), E=94α MeV, respectively.
In 2006Kh08, 57.08 MeV/α beams of 30Al impinged on a Si target, measured σ=2281 mb 515 for the Si(30Al,x) reaction and a reduced strong absorption radius of <r02>=1.2 fm2 3 is deduced and used to study the isospin dependence. 1999Ai02 at E=43.40 MeV/α measured σ=2047 mb 124 and <r02>=1.12 fm2 7.
1997Vo03: Production cross section σ < 0.29 mb was measured for 30Al production from 56Fe+800 MeV protons determined by activation.
1971Ar32: 232Th(40Ar,X), E=290 MeV; measured fragments isotopic yields.
1963Pe25: Si(n,X), E=14 MeV, measured a half-life of 72.5 s 13 from 2.5-3.5γ(t). In 1963Pe25, the activity was speculated from 30mAl - not confirmed by any other work. No comparable g.s. or isomeric half-life is present for the isotopes from the 28,29,30Si(n,X), X=p,n’,α, reactions. 1971Gr19 searched for the 72.5 s 30mAl state and did not find any.
