Effect of compound nuclear reaction mechanism in 12C(Li6,d) reaction at sub-Coulomb energy

open access: yesPhysics Letters B, 2017
The angular distribution of the 12C(Li6,d) reaction populating the 6.92 and 7.12 MeV states of 16O at sub-Coulomb energy (E=cm3 MeV) are analysed in the framework of the Distorted Wave Born Approximation (DWBA).

A study on the reaction between CO2 and alkanolamines in aqueous solutions [PDF]

open access: yes, 1983
Literature data on the rates of reaction between CO2 and alkanolamines (MEA, DEA, DIPA, TEA and MDEA) in aqueous solution are discussed. These data induced us to carry out absorption experiments of CO2 into aqueous DEA, DIPA, TEA and MDEA solutions from ...
