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:

Time-Dependent Nuclear Decay Parameters: New Evidence for New Forces?
Ephraim Fischbach,J. B. Buncher,J. T. Gruenwald,Jere H. Jenkins,Dennis E. Krause,J. J. Mattes,J. R. Newport +6 more
TL;DR: The question of whether nuclear decay rates (or half-lives) are time-independent constants of nature, as opposed to being parameters which can be altered by an external perturbation has been discussed in this paper.

Evidence against correlations between nuclear decay rates and Earth–Sun distance
Eric B. Norman,Eric B. Norman,Eric B. Norman,Edgardo Browne,Howard A. Shugart,Tenzing H. Y. Joshi,Richard B. Firestone +6 more
TL;DR: In this article, the authors reexamined their previously published data to search for evidence of correlations between the rates for the alpha, beta-minus, beta plus, and electron capture decays of 22Na, 44Ti, 108Agm, 121Snm, 133Ba, and 241Am and the Earth?Sun distance.

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.
