Samenvatting

Recent data on isoscalar giant monopole resonance (ISGMR) in the calcium isotopes ^40,44,48Ca have suggested that K_τ, the asymmetry term in the nuclear incompressibility, has a positive value. A value of K_τ>0 is entirely incompatible with present theoretical frameworks and, if correct, would have far-reaching implications on our understanding of myriad nuclear and astrophysical phenomena. This paper presents results of an independent ISGMR measurement with the ^40,42,44,48Ca(α,α^′) reaction at E_α=386 MeV. These results conclusively discount the possibility of a positive value for K_τ, and are consistent with the previously-obtained values for this quantity.
