30SI c 1974Al09: {+30}Al was produced in the {+18}O({+18}O,|apn), E=42 MeV,
30SI2c reaction at one of the Brookhaven MP tandem Van de Graaff accelerators.
30SI3c Ge(Li) detector; measured E|g, I|g.
30SI c 1974Kl07: {+30}Al was produced in the {+30}Si(n,p), E=14.5 MeV,
30SI2c reaction; Ge(Li) detector; Measured E|g, I|g.
30SI c 1961Ro12: {+30}Al was produced in the {+30}Si(n,p), E|?24 MeV neutron
30SI2c from {+7}Li(d,n) reaction with 9.7-MeV external deuteron beam from the
30SI3c Purdue University 37-in. cyclotron. Detectors: NaI(Tl) and plastic
30SI4c phosphor coupled with photomultiplier tube. Measured E|g,
30SI5c E{-|b_end}=5.05 MeV {I25}, deduced |b feeding to the 1st and 2nd
30SI6c excited states.
30SI cB IB$Based on the measured |b spectra and deduced values from E|g, I|g
30SI2cB in 1961Ro12, 1974Kl07, and 1974Al09. Intensity balance of |g transition
30SI2cB at the 1st excited level indicates that feeding from higher lying
30SI3cB levels is missing.
30SI cB IB(B) From 1974Kl07. For missing and weaker |g transitions, authors
30SI4cB estimated |b feeding considering E|g and I|g from the literature.

30SI cG RI(D)$Not reported in 1974Kl07, I|g scaled to the adopted |g branching
30SI2cG and adjusted for the beta feeding to the level.

30SI cL E$From a least squares fit to the |g-ray energies, assuming |DE=0.5 keV
30SI2cL for missing uncertinty.
