01 Jun 1986-Earth and Planetary Science Letters (Elsevier)-Vol. 78, Iss: 2, pp 168-176
TL;DR: 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.

TL;DR: In this article, the experimentally determined properties of energy levels of A = 21−44 nuclei are compiled and evaluated with emphasis on nuclear spectroscopy, and the available information on excitation energies, spins, parities, isospins, lifetimes or widths and observed decay is summarized in a master table.

TL;DR: In this article, a negative correlation between bioturbation rate and tracer half-life was found in deep-sea sediments, and the authors hypothesize that this negative relationship results from age-dependent mixing, a process in which recently sedimented, food-rich particles are ingested and mixed at higher rates by deposit feeders than are older, foodpoor particles.

TL;DR: The state of the art in accelerator mass spectrometry (AMS) is reviewed in this article, with an emphasis on post-1990 developments and literature, and a very wide spectrum of applications that now employ AMS, and groups these according to research area rather than isotope.
Abstract: The state of the art in accelerator mass spectrometry (AMS) is reviewed. The review is divided in two parts. The first covers the general methodology, followed by its specific elaborations for the commonly measured long-lived isotopes such as 10Be, 14C, 26Al, 36Cl and 129I, as well as other isotopes with emerging applications. The second part considers the very wide spectrum of applications that now employ AMS, and groups these according to research area rather than isotope. The period up until late 1998 is covered, with an emphasis on post-1990 developments and literature.

Subsequently, Alburger et al (1986), who followed the decay of a32Si source over a period of about four years, reported a value of 172±4 a which differs by 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.
Abstract: The half-life of /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. The new value was obtained by measuring the specific ..beta.. activity with a liquid--scintillation-counter technique and the /sup 32/Si concentration with tandem-accelerator mass spectrometry. It is expected that the present result will have a strong impact on studies with cosmogenic /sup 32/Si.

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.

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.
Abstract: 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. The result obtained, 108 plus or minus 18 yr, disagrees with the accepted value of 330 plus or minus 40 yr. The implications of the new half-life of Si-32, which is used for dating studies, are discussed.
