Feshbach resonances in D + HD(v = 1, j = 0) reaction are studied by using the time‐independent quantum method. The integral cross section (ICS) results present three Feshbach resonance peaks, which are different from H + HD(v = 1, j = 0) reaction dominated by only one peak. These resonances are attributed to coupling with adiabatic effective potentials of D + HD(v = 1, j = 1) reaction, and the most obvious peak is contributed by J = 1 at 83.16 cm−1 collision energy. For J = 0 and 2, the resonances are related with the same L partial wave and present a double‐peak structure in total ICS. The characteristics of product angular distribution show that the resonance of J = 1 is long‐lived, while the lifetimes are relatively shorter for the resonance of J = 0 and 2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
