General Comments:

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, reactions, 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.

Q-value: Q(β-)=8561 14, S(n)=5728 14, S(p)=12542 20, S(α)=-11435 15 (2003Au03)
