General Comments:

First isotope identification by 1971Ar32.

1971Ar32: 232Th(40Ar,X)35Si, E=290 MeV on the 310 cm heavy-ion cyclotron in Dubna. Measured fragments isotopic yields. Deduced evidence for fragments.

1986Du07, 1988DuZT: 9Be(40Ar,X)35Si, E=60 MeV/nucleon at GANIL. Measured βγ-coin, T1/2.

1999Ai02: Cross section measurement in Si(35Si,X) E=38-80 MeV/ nucleon at the NSCL facility. Deduced strong absorption radius

1997Fo01: 208Pb(37Cl,X)35Si, E=230 MeV at the Legnaro superconducting linear accelerator ALPI. Measured γγ-coin, yield.

1999YoZW: Fragmentation of 48Ca beam at 70 MeV/nucleon by 9Be and 181Ta targets at RIKEN. Measured half-life and delayed-neutron branches.

2006Kh08: Secondary beams produced by fragmentation of 48Ca beam at 60.3 MeV/nucleon by 181Ta targets at GANIL. Used a silicon telescope as both reaction target and detection system. Measured energy-integrated reaction cross-sections. Deduced radii, isospin dependence.

2006Ro34: 2H(42S,X)35Si at E=99.8 MeV/nucleon, at the NSCL facility. Measured production cross section.

2007No13: Fragmentation of 40Ar beam at 100 MeV/nucleon on 9Be and 181Ta targets at GANIL. Measured momentum distribution and cross sections.

Mass measurements: 1986Fi06, 1986Sm05, 1984Ma49

This nuclide is of possible relevance to "island of inversion " near n=20.

Q-value: Q(β-n)=2120 40, S(2n)=9990 40, S(2p)=33900 40 (2012Wa38)
