Half-life of32Si
TLDR
In this paper, the decay rate was determined from the 32Si/36Cl ratio of counts, based on the analysis of 53 points taken in 48 months, the valueT1/2 = 172(4) yr is adopted for the half-life of 32Si.About:

Spectral Content of 22Na/44Ti Decay Data: Implications for a Solar Influence
Daniel O'Keefe,Brittany L. Morreale,R. H. Lee,J. B. Buncher,Ephraim Fischbach,Tom Gruenwald,Jere H. Jenkins,D. Javorsek,Peter A. Sturrock +8 more
TL;DR: In this article, a more detailed analysis of both amplitude and phase of the Norman data was performed and it was shown that the amplitude and the phase of these data actually favor the presence of an annual variation in the decay ratio, albeit weakly.

Detection of 32Si and 36Cl with the ETH/SIN EN-Tandem
TL;DR: In this paper, the reproducibility of 36 Cl measurements with a beam energy of 48 MeV was investigated with the case of 32 Si and successful efforts were made to determine absolute isotope ratios of artificially enriched silicon samples.

Ultra-sensitive particle identification systems based upon electrostatic accelerators
TL;DR: In this paper, a review is presented of a new ultra-sensitive particle identification technique which uses as one component an electrostatic accelerator, which has been used in various laboratories for a search for superheavy elements, quarks, and the long lived isotopes 14 C and 36 Cl.
