Novae in a test-tube: Investigating the 21Na(ρ,γ)22Mg reaction at TRIUMF's ISAC facility

Sodium 21

The 21Na(ρ,γ)22Mg reaction is expected to play an important role in the synthesis of intermediate mass elements in Oxygen-Neon novae. The first direct measurement of the rate of this reation was completed using the DRAGON recoil mass separator at TRIUMF's ISAC facility. The energy of one resonance important in the reaction was measured to be Ec.m.=728.1 ± 1.2 keV, and its resonance strength was determined to be ωγ= 254 ± 16stat ± 44sys meV.
