Targetry for cyclotron production of no-carrier-added cadmium-109 from natAg(p,n)109Cd reaction
Background: Solid targets that consist of powder and electrodeposited targets are used commonly to produce radionuclides by accelerators. Since silver is easily electrodeposited in cyanide baths and has a very excellent thermal conductivity, the electrodeposited target is preferable to produce 109Cd. To avoid cracking or peeling of the target during bombardment, it should have a level surface a...
متن کاملAsymptotic normalization coefficient from the 12 C ( 7 Li , 6 He ) 13 N reaction and the astrophysical 12 C ( p , γ ) 13 N reaction rate
Angular distribution of the 12C(7Li,6He)13N reaction at E(7Li) = 44.0 MeV was measured at the HI-13 tandem accelerator of Beijing, China. Asymptotic normalization coefficient (ANC) of 13N → 12C + p was derived to be 1.64 ± 0.11 fm−1/2 through distorted wave Born approximation (DWBA) analysis. The ANC was then used to deduce the astrophysical S(E) factors and reaction rates for direct capture in...

متن کاملTheoretical Investigation of the Reaction Mechanism for a Type of N-heterocyclic Compound Involving Mono-N-aryl-3-aminodihydropyrrol
The kinetics of reaction between 4-methylaniline (1), dimethyl acetylenedicarboxylate (2) and formaldehyde (4) has been theoretically investigated to gain further insight into the reaction mechanism. The results of theoretical calculations were achieved using the ab initio method at the HF/6-311g (d, p) level of theory in gas phase. The mechanism of this reaction had 5 steps. Theoretical kineti...
متن کاملSPECTROPHOTOMETRIC REACTION RATE METHOD FOR THE DETERMINATION OF NITRITE BY CATALYTIC ACTION ON NILE BLUE A BROMATE REACTION
A kinetic method developed for the determination of ultra-trace amounts of nitrite based on its catalytic effect on the reaction between potassium bromate and Nile blue A in strongly acidic media is reported. The reaction was monitored spectrophotometrically by measuring the decrease in absorbance of Nile blue A at 645 nm by the fixed-time method. The decrease in absorbance during the first...
