Study of the 7Be(d,3He)6Li* reaction at 5 MeV/u

open access: yesPhysics Letters B
The measurement of the 7Be(d,3He)6Li* transfer cross section at 5 MeV/u is carried out. The population of the 2.186 MeV excited state of 6Li in this reaction channel is observed for the first time.

Updated Big Bang nucleosynthesis bounds on long-lived particles from dark sectors

open access: yesPhysics Letters B
As electromagnetic showers may alter the abundance of Helium, Lithium, and Deuterium, we can place severe constraints on the lifetime and amount of electromagnetic energy injected by long-lived particles.
