Experimental and theoretical studies of hyperfine structures in ${}^{21}$Na

Junho Won, Jeongsu Ha, Deuk Soon Ahn +38

We measured the hyperfine structure constants, $A(3s^2{S}_{1/2})$ and $A(3p^2{P}_{1/2})$, of the neutron-deficient isotope ${}^{21}\text{Na}$ using CLaSsy, a setup dedicated to collinear…
