General Comments:

Mass measurement: 35.98130226 u 42 (2007Ya08) using ISOLTRAP at ISOLDE-CERN facility

1967Be11: 36K produced and identified in 36Ar(p,n) reaction at 23 MeV, measured half-life and γ radiation

1971Ja09: 36Ar(p,n) E=13.8-14.1 MeV, deduced Q value and half-life of 36K g.s.

1972Mi13, 1971Ja09 (also 1971MiZS): decay of 36K formed in 36Ar(p,n) reaction, measured Eγ, Iγ

1972Mo08, 1971Jo08: measured T1/2 of 36K

1976Fr03: decay of 36K

Later studies of 36K decay: 1996Il02 (also 1997Il03), 1995Yo04, 1980Es01 and 1980Ew01

Q-value: Note: Current evaluation has used the following Q record

Q-value: Q(εp)=4307.21 35, S(2n)=32340 298 (syst), S(2p)=7555.3 4 (2011AuZZ)

Q-value: Values in 2003Au03: Q(β-)=-10990 40, S(n)=14329 21, S(p)=1668 8, Q(α)=-6521 10, S(2n)=32090 300 (syst), S(2p)=7564 8
