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:

Environmental Isotopes in the Atmosphere and Hydrosphere
TL;DR: Isotope hydrology involves hydrologic work, particularly regarding groundwater, using both environmental and artificially introduced isotopes, some of which constitute part of the water molecule itself.

Investigation on possible systematics and side processes
R. Bernabei,P. Belli,A. Di Marco,A. d’Angelo,A. Incicchitti,F. Cappella,R. Cerulli,C. J. Dai,Xiuhua Ma,Z. P. Ye +9 more
TL;DR: In this paper, the main arguments and reasons which allowed one to exclude either systematic effects or side processes as possible sources of the annual modulation observed in the former DAMA/NaI and the latter DAMA-LIBRA-phase1 datasets were gathered.

Isobar separation of 32Si from 32S in AMS using a passive absorber
Matthias Schlomberg,Christof Vockenhuber,Hans-Arno Synal,M. Veicht,Ionut Mihalcea,Dorothea Schumann +5 more
TL;DR: In this paper , an accelerator mass spectrometry (AMS) method was developed to detect 32 Si and separate it from its intense isobar 32 S. This separation was achieved using a passive absorber cell in front of a gas ionization chamber at an energy of 30 MeV at the 6 MV Tandem accelerator at the Laboratory of Ion Beam Physics (LIP) at the ETH Zurich.

Test of nuclear decay rate variation due to an antineutrino flux
TL;DR: In this paper , the authors reviewed the state of decay rate parameter variations experiments and placed them into a common comparable context by defining a phenomenological cross section, and then they made decay parameter measurements as a function of time at the level of $10.5$ in the presence of an antineutrino flux with an on-off cycle time of $30 days.

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.
