Deriving Iodine-free spectra for high-resolution echelle spectrographs [PDF]
, 2019 We describe a new method to derive clean, iodine-free spectra directly from observations acquired using high-resolution echelle spectrographs equipped with iodine cells. The main motivation to obtain iodine-free spectra is to use portions of the spectrum that are superimposed with the dense forest of iodine absorption lines, in order to retrieve lines ...

A compact iodine-laser operating at 531 nm with stability at the 10$^{-12}$ level and using a coin-sized laser module [PDF]
Opt. Express 23, 20749 (2015), 2015 We demonstrate a compact iodine-stabilized laser operating at 531 nm using a coin-sized light source consisting of a 1062-nm distributed-feedback diode laser and a frequency-doubling element. A hyperfine transition of molecular iodine is observed using the light source with saturated absorption spectroscopy.

The puzzles of dark matter searches
, 2009 Positive results of dark matter searches in DAMA/NaI and DAMA/LIBRA experiments, being put together with negative results of other groups, can imply nontrivial particle physics solutions for cosmological dark matter.

Determination of fission fragment yields using the sorbtion process [PDF]
Ядерна фізика та енергетика, 2007 The separation of iodine isotopes from the sum of 235U fission products by the sorption process from water solution using coal sorbent SKS was investigated. The sorption coefficient values in range 0,7 - 0,9 was obtained.

Superconducting High Pressure Phases Composed of Hydrogen and Iodine [PDF]
, 2015 Evolutionary structure searches predict three new phases of iodine polyhydrides stable under pressure. Insulating P1-H5I, consisting of zigzag chains of HI (delta+)and H2(delta-) molecules, is stable between 30-90 GPa. Cmcm-H2I and P6/mmm-H4I are found on the 100, 150 and 200 GPa convex hulls.

Observations of Fallout from the Fukushima Reactor Accident in San Francisco Bay Area Rainwater [PDF]
, 2011 We have observed fallout from the recent Fukushima Dai-ichi reactor accident in samples of rainwater collected in the San Francisco Bay area. Gamma ray spectra measured from these samples show clear evidence of fission products - 131,132I, 132Te, and 134,
