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:

Solar influence on nuclear decay rates: constraints from the MESSENGER mission
Ephraim Fischbach,K. J. Chen,Robert E. Gold,John O. Goldsten,David J. Lawrence,R. J. McNutt,Edgar A. Rhodes,Jere H. Jenkins,James M. Longuski +8 more
TL;DR: In this paper, the authors analyzed the 137C decay data from a small sample onboard the MESSENGER spacecraft en route to Mercury, with the aim of setting limits on a possible correlation between nuclear decay rates and solar activity.

Half-life of 32Si measured via accelerator mass spectrometry
TL;DR: The half-life of 32 Si has been remeasured by a method in which the isotopic ratio and the activity ratio of 32 si and 31 Si, produced in charged-particle reactions on the same target, were determined by means of accelerator mass spectrometer (AMS) and β spectrometry, respectively as mentioned in this paper.

Non-dependence of nuclear decay rates of 123I and 99mTc on Earth-Sun distance.
TL;DR: This study prospectively looks at two radionuclides which have not previously been studied for annual variation, 123I and 99mTc, and finds no significant periodicity and no evidence for a period of 1 year.

A.H. Wapstra,Georges Audi +1 more
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.
