General Comments:

Everywhere in comments in this dataset "36Ar(p,p) " is used as abbreviation for "36Ar(p,p),(p,p’),(p,γ),(p,p’γ):resonances "

Isotope shift and quadrupole moment measurement: 1997Be35

Q-value: Note: Current evaluation has used the following Q record -11664.47 80 15454.2 4 1857.63 9-6221.8 5 2011AuZZ

Q-value: S(2n)=29769.93 52, S(2p)=10364.62 10 (2011AuZZ).

Q-value: Values in 2003Au03 are slightly different: Q(β-)=-11638 22, S(n)=15445 8, S(2n)=29774 20. Others are the same as in 2011AuZZ

E(γ): Deduced by evaluators from differences of initial and final levels, except for few gammas noted in the table whose Eγ’s were measured precisely. Most of the γ rays originate in the 36Ar(p,p) dataset.

I(γ): From 36Ar(p,p), unless noted otherwise
