The ^{13}C(α,n)^{16}O reaction is the main neutron source for slow-neutron-capture process in asymptotic giant branch stars and intermediate process. Direct measurements at astrophysical energies above-ground laboratories are hindered by extremely small cross sections vast cosmic-ray-induced background. We performed first consistent direct measurement range of E_{c.m.}=0.24 to 1.9 MeV using accelerators China Jinping Underground Laboratory Sichuan University. Our covers almost entire Gamow...
Abstract An E parallel B type neutral particle analyzer (E//B NPA) with mass and energy resolution has been developed successfully conducted its first experiment on the HL-3 tokamak. The calibration of E//B NPA was performed using H + D beams a 300 kV ion accelerator. Results indicate that is capable detecting in range 27.4 keV to 462.4 15.6 233.4 keV, an less than 10%. Thanks background resolving ability LYSO+SiPM detector module, novel method employed for data analysis during Background...
The K-shell ionization cross sections of Ni and Cr by electron impact have been measured. In the measurements thin targets with a thick substrate were used. influence reflected electrons from on has corrected means detailed calculation transport. By comparison it is shown that measurement data section are in good agreement existing experimental data.
The experimental measurement of electron-impact K-shell ionization cross sections Cu and Co elements within the energy region 8--25 keV was reported. influence a substrate thin targets on has been corrected by method based upon bipartition model electron transport [Z. M. Luo, Phys. Rev. B 32, 812 (1985); 824 (1985)]. measured are in good agreement with existing data well reproduced empirical formula Green Cosslett [Proc. Soc.

Au Lα and Lβ Ag L-shell x-ray production cross-sections by electron impact have been measured in the incident energy region from near threshold to about 25 keV. Thin films with thick aluminium substrates were used as targets experiments. The effect of directional spreading beam within active enhancement due backscattering electrons bremsstrahlung photons are corrected means Monte Carlo simulations. experimental data provided this method compared calculated a PWBA theory Coulomb, relativistic...
The measurement of Lα, Lβ x-ray production cross sections for the element Pb (Z = 82) by 16–40 keV electron impact is reported in this paper. target used experiment was prepared evaporating elemental onto a thick pure carbon substrate. effects multiple scattering electrons when penetrating film, reflected from substrate and bremsstrahlung photons produced incident on are corrected using Monte Carlo method. experimental data, here first time energy region interest, compared with plane-wave...
In this paper, the $K$-shell ionization cross sections of Si element in threshold energy region 3--25 keV have been measured by using thick-target method. With Monte Carlo simulations, effects multiple scattering incident electrons and from bremsstrahlung photons other secondary particles method discussed. The detection efficiency calibration lower-energy has performed spectra thick carbon target electron impact combination with use standard x-ray sources, detector thickness parameters also...
Abstract In order to understand the impact of microorganisms on fate thorium in soils, we investigated biosorption behavior and corresponding mechanisms by cells Geotrichum sp. dwc-1, one dominant species fungal group isolated from 3.5 m depth soil layer Southwest China. It was observed that fast adsorption onto G . dwc-1 could take place, with a high distribution coefficient K d (0.93 mL/mg) obtained, when dwc-1and concentrations were 5 g/L 10 mg/L, respectively. The dependent pH value,...
Abstract The chemi‐crystallization and free volume changes of high‐density polyethylene (HDPE) exposed to subtropical humid climate Guangzhou, China, were investigated using Fourier transform infrared spectroscopy, differential scanning calorimetry, wide‐angle X‐ray diffraction, dynamic mechanical analysis positron annihilation lifetime spectroscopy. An increase in content carbonyl groups significant observed occur during natural exposure. Chain scission accounted for the would lead greater...
In this paper, the Tikhonov regularization method and classical molecular dynamics are used to deal with inverse problem involved in measurement of inner-shell ionization cross sections by using thick-target method. These two methods applied simulated real experimental data for $K$-shell a Ni element electron impact. The satisfactory results can be obtained these treat estimated total error described paper is about 10%, which same order as thin-target It concluded that reliably future or...
