General Comments:

1977Tr03: First report on 36Ca nuclide from mass excess in reaction: 40Ca(4He,8He), deduced mass excess.

1981Ay01: First identification of this nuclide in reaction: 40Ca(3He,α3n) at 95 MeV. Measured delayed proton decay and isotopic half-life; Berkeley cyclotron facility and recoil-atom mass analyzer.

1995Ga16: 36Ca produced using a radioactive ion beam from ISOLDE online isotope separator with a Ti target at CERN, measured delayed proton decay of 36Ca.

1997Tr05, 1995Tr02: 36Ca produced by fragmentation of 40Ca beam with a 9Be target at 300 MeV/nucleon beam energy, fragments separated using FRS facility at GSI. Measured delayed proton branches and isotopic half-life.

2001Lo11: 36Ca produced by fragmentation of 40Ca beam at 95 MeV/ nucleon with Ni target, fragments separated with LISE3 spectrometer at GANIL facility. Measured delayed proton branches.

2007Do11, 2007Bu15: 9Be(37Ca,Xγ) one-neutron knockout reaction (GSA and GANIL), identification of first 2+ state

36Sc nuclide which can possibly decay by β to 36Ca is not yet identified

37Sc nuclide which can possibly decay by protons to 36Ca is not yet identified

37Ti nuclide which can possibly decay by β-delayed protons to 36Ca is not yet identified

38Ti nuclide which will most likely decay by two-proton emission to 36Ca is not yet identified but its search and upper limit of 120 ns for half-life has been reported by 1996Bl21

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

Q-value: Estimated ΔS(n)=200 (2011AuZZ)

Q-value: Q(εp)=9307 40, S(2n)=36445 301 (syst), S(2p)=2652 40 (2011AuZZ)

Q-value: Values in 2003Au03: S(n)=19110 200 (syst), S(p)=2560 40, Q(α)=-6660 40, S(2n)=35740 300 (syst), S(2p)=2640 40, Q(εp)=9320 40
