    • Gamma irradiation effects on polymethyl methacrylate 

      Al-Qaradawi, I. Y.; Abdulmalik, D. A.; Madi, N. K.; Almaadeed, M. ( WILEY-VCH Verlag , 2007 , Article)
      The effect of gamma-irradiation on the structure of polymethyl methacrylate (PMMA) has been investigated. In this study, the PMMA specimens were gamma-irradiated at doses in the range of 0-1000 kGy and measured by means ...

    • Positron annihilation studies of the effect of gamma irradiation dose in polymers 

      Al-Qaradawi, I. Y.; Britton, D. T.; Abdel-Hady, E. E.; Abdulmalik, D. A.; Al-Shobaki, M. A.; ... more authors ( Elsevier Ltd , 2003 , Conference Paper)
      Positron annihilation lifetime (PAL) technique has been applied to study the effect of gamma irradiation dose on the structure of low-density polyethylene and polystyrene. The positron annihilation lifetime measurements ...

    • Self-implantation of Cz-Si: Clustering and annealing of defects 

      Abdulmalik, D. A.; Coleman, P. G.; Al-Qaradawi, I. Y. ( Elsevier , 2006 , Article)
      Observations of vacancy clusters formed in Czochralski (Cz) Si after high energy ion implantation are reported. Vacancy clusters were created by 2 MeV Si ion implantation of 1 × 10 15 ions/cm 2 and after annealing between ...
