In the present study we consider the gamma radiation field formed by an isotropic point source (with quantum energies E0= 0.661, 1.0, 1.38, and 2.62 MeV) situated in a semiinfinite absorber (aluminum) at depths H equal to 0, 0.5, 1, and 2 mean free paths of the primary radiation. ...
A field-oxide structure for radiation-hard CMOS VLSI is described. It is a three-layer structure consisting of a thin thermal oxide, a doped polysilicon sh... Manchanda,L.,Hillenius,... - 《Electron Device Letters IEEE》 被引量: 20发表: 1989年 ChemInform Abstract: SOLVENT‐EXTRACTION COMPLE...
focusing in particular on those electronswhose radiation falls within the energy detection range of the BATSE detectors.We find that in order to produce the rapid variability observed in most burststhe magnetic energy density in the shocked material must be greater than about1\% of the thermal ene...
radiation-induced cross-linkingThe changes in the carbonyl index, the melt flow rate, the crystalline content and the ultimate tensile properties of metallocene linear low density polyethylene (mLLDPE) films subjected to gamma irradiation from 10 to 800kGy, were investigated with and without hindered...
Effect of gamma irradiation on molecular structure and physicochemical properties of corn starch. Carboxyl content and amylose leaching of gamma-irradiated corn starch increased and swelling factor decreased with increasing radiation dose. The apparent ... H.㎎.

The radiations from such electrons cover the entire range of wave lengths, from radio wave to gamma-rays, depending on the physical parameters such as the electron energy or radius of motion. They possibly play important roles with their angular momentum in nature and in laboratories, which ...

A decay scheme of 74Zn to levels in 74Ga is presented in which 39 γ rays are placed, deexciting 11 states up to 1085 keV. Five levels are postulated to have Jπ=1+ based on β feedings but much uncertainty still exists concerning Jπ assignments for levels below 300 keV.关键词:nucl...
Using in-beam technique, gamma radiation from excited levels in the even Xe isotopes A = 124, 126, 128, 130 and 132 has been studied. The nuclei are produced in (α, 2n) reactions on enriched Te targets at a bombarding energy of about 28 MeV. From intensity and angular distribution mea...
