摘要:Abstract(#br)The production of protons, anti-protons, neutrons, deuterons and tritons in minimum bias p+C interactions is studied using a sample of 385 734 inelastic events obtained with the NA49 detector at the CERN SPS at 158 GeV/c beam momentum. The data cover a phase spa...

摘要:The microreliefs of the fractured surfaces of non-irradiated low density polyethylene (LDPE) and gamma irradiated high density polyethylene (HDPE) “BULEN” are similar, but are obtained due to different microdestruction mechanisms determined by different interaction mechanism...

摘要:Isotactic polypropylene (iPP), irradiated by a Co60 gamma source, has been investigated. A correlation between the shear rate and the physical and chemical crosslinking density of the macromolecular chains at irradiation is given. The electron microscopy analysis (EMA), thermal-m...

摘要:Abstract(#br)The effect of gamma irradiation on non-isothermally crystallized low density polyethylene (LDPE) has been studied by thermal-mechanical analysis (TMA) and transmission and scanning electron microscopy (TEM and SEM, respectively). Analysis of the TMA curves of th...
