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:

Advances in accelerator mass spectrometry
TL;DR: In this article, the detection of some of the most important cosmogenic long-lived radioisotopes using the technique of accelerator mass spectrometry, in particular, the developments in accuracy approaching 0.3% for 14 C and 1.1% for 10 Be, 26 Al, 36 Cl and the improvement of the detection limits at low acceleration voltages, are discussed.

TL;DR: In this paper, the running-mean of the power spectrum was investigated, and a major peak at 11.18 year−1 with power 4.08 was identified, and the significance of this peak in terms of the false-alarm probability was evaluated by means of the shuffle test and also by a new test (the "shake" test) that involves small random time displacements.

Silicon-32 as a tool for dating the recent past
L. Keith Fifield,Uwe Morgenstern +1 more
TL;DR: In this article, the authors review efforts to determine the half-life of 32Si, survey the detection methods, and discuss the applications of this radioisotope chronology, and show that at least some of the chronometric potential of 32P is close to being realised as a result of recent improvements in methods of measurement.

Oscillations in radioactive exponential decay
TL;DR: In this article, it was shown that the measured effects observed in some of the cases, namely in the decay of 226Ra, 32Si in equilibrium, and 36Cl, can be explained with the temperature variations.

A new determination of the half-life of 32Si
Hansjakob Hofmann,G. Bonani,M. Suter,Willy Wolfli,D. Zimmermann,D. Zimmermann,H. R. von Gunten,H. R. von Gunten +7 more
TL;DR: In this paper, the half-life of Si has been redetermined from different Si-samples produced by proton activation of 37 Cl (as LiCl) and neutron activation of 31 P (as Mg 2 P 2 O 7 ).

TL;DR: The present table gives values and their estimated precision for the separation energies and reaction energies representing together twelve carefully selected combinations of nuclides with ΔA as discussed by the authors, where ΔA is defined as the ratio of the separation energy and reaction energy.

Measurement of the /sup 32/Si half-life via accelerator mass spectrometry
W. Kutschera,W. F. Henning,Michael Paul,Robert Smither,E. J. Stephenson,J.L. Yntema,D.E. Alburger,J.B. Cumming,G. Harbottle +8 more
TL;DR: The half-life of cosmogenic /sup 32/Si has been measured to be T/sub 1/2/=101 +- 18 yr, considerably shorter than the previously accepted value of approx. =300 yr.

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.

Half-life of Si-32 from tandem-accelerator mass spectrometry
David Elmore,N. Anantaraman,H. W. Fulbright,Harry E. Gove,H. S. Hans,K. Nishiizumi,M. T. Murrell,Morihiro Honda +7 more
TL;DR: In this paper, a newly developed mass-spectrometry technique employing a tandem Van de Graaff accelerator together with a special beam-transport system and heavy-ion detector has been used to determine the half-life of Si-32.
