The structure of S44 has been studied by using delayed γ and electron spectroscopy. The decay rates of the 02 + isomeric state to the 21 + and 01 + states, measured for the first time, lead to a reduced transition probability B(E2:2 1 +→02 +)=8.4(26)e 2fm4 and a monopole strength ρ2(E0:02 +→01 +)=8.7(7)×10-3. Comparisons to shell model calculations point towards prolate-spherical shape coexistence, and a two-level mixing model is used to extract a weak mixing between the two configurations.
