General Comments:

2005Ha30,2002Sa38,2002Va21,2001Ju06: Calculated level energies.

2006Ya17: production cross section in 80Kr on a beryllium target, E=1.05 GeV/α

1988Bu12: 66As produced from 58Ni(10B,2n) at E(10B)=29.5 and 30.5 MeV; T1/2 from rapid-transport target system and β-ray range telescope.

1978Al23: 66As produced by 58Ni(10B,2n) at E=30 MeV; T1/2 from chopped beam β+ counting

1976JaZP: also by 40Ca(32S,npα) and 50Cr(19F,3n) reactions.

Theory, calculations: 2008To03, 2007Ha48
