ESR/Alanine γ-dosimetry in the 10–30 Gy range
Abstract We report Alanine Dosimeter preparation, procedures for using the ESR/Dosimetry method, and the resulting calibration curve for γ-irradiation in the range from 10–30 Gy. We use calibration… Expand
Resonant Raman scattering and optical transmission studies of CuÑIIÖ and FeÑIIIÖ impurities in crystalline L-alanine
A comparative study by means of resonant Raman scattering and optical transmission spectroscopy between the different color centers originating from Fe~III! and Cu~II! doping of L-alanine crystals is… Expand
ESR/Alanine gamma-dosimetry in the 10-30 Gy range.
We report Alanine Dosimeter preparation, procedures for using the ESR/Dosimetry method, and the resulting calibration curve for gamma-irradiation in the range from 10-30 Gy. We use calibration curve… Expand
FE IMPURITIES IN L-ALANINE : AN EPR, LUMINESCENCE, AND RAMAN STUDY
We present a study of low concentration Fe~III! doping in crystalline L-alanine by means of electron paramagnetic resonance, resonant Raman scattering, and photoluminescence. The magnetic resonance… Expand
Luminescence and resonant Raman scattering of color centers in irradiated crystalline L-alanine
The color centers in electron irradiated L-alanine crystals are studied by means of resonant Raman scattering and photoluminescence. We find a selective resonant enhancement of some of the… Expand
Logarithmic-to-nonlogarithmic flux-creep transition and magnetic-flux hardening in Bi-Sr-Ca-Cu-O superconducting ceramics.
A sharp temperature- and field-dependent transition from a logarithmic to a nonlogarithmic flux-creep behavior has been found in Bi-Sr-Ca-Cu-O superconductors. The transition is not followed by any… Expand
X-ray diffraction, Raman, infrared and Mössbauer spectra of heavily Fe doped Bi2Sr2Ca1Cu2O8+d
Abstract We report measurements on x-rays diffraction and Raman, infrared and Mossbauer absorption spectra of Bi2Sr2Ca1(Cu1−x, Fex)2O8+δ, 0·05≤x≤0·25. X-ray analysis shows that the increment of Fe in… Expand
