First isotope identification by 1985Ay01
1985Ay01: 35Ca produced by bombarding a 2 mg/cm2 natural calcium target with 135 MeV 3He beam of 3-7 μA from the 88 inch cyclotron at the Lawrence Berkeley Laboratory. Measured Ep, Ip. Deduced mass excess (4453 keV 60).
1986La17: E=77.4 MeV/nucleon 40Ca beam from GANIL on Ni target. α four stage telescope (two 1000 μm Si detectors and two 4000 μm Si(Li) detectors) for detecting fragments. Measured fragment spectra. Deduced fragment mass, charge distribution.
1999Tr04,1998Le45: 35Ca (98% purity, 0.3 ions/s) beam produced by fragmentation of a 95 MeV/nucleon 40Ca20+ beam of 400 enA on a rotating 500 μm natural Ni target, and implanted into a 500 μm silicon detector for detecting βp and β2p decays. Two silicon counters for detecting β-rays and three Ge detectors and two NaI detectors for detecting γ-rays. Measured βpγ-coin, Ep, Ip, T1/2. Deduced levels for 35K.

Q-value: Note: Current evaluation has used the following Q record 17135 syst 1281 syst-8931 syst 2011AuZZ
Q-value: Estimated uncertainties: ΔS(n)=ΔS(p)=357, ΔQ(α)=284 (2011AuZZ)
Q-value: Q(εp)=15876 196, S(2p)=406 196 (2011AuZZ); both from systematics
Q-value: Values in 2003Au03: S(n)=16620 360, S(p)=1210 360, Q(α)=-9120 280, S(2p)=590 200; all from systematics
