Two recent studies of the evolution of the isoscalar giant monopole resonance (ISGMR) within the calcium isotope chain report conflicting results. One study suggests that the monopole resonance energy, and thus the incompressibility of the nucleus $K

Multi-probe study of excited states in $\mathrm{^{12}C}$: disentangling the sources of monopole strength between the Hoyle state and $E_{x} = 13$ MeV

N., Nemulodi, F., Pellegri, L., Pesudo, V., Wiedeking, M., Buthelezi, E. Z., Chudoba, V., Förtsch, S. V., Jones, P., Kamil, M., Mira, J. P., O'Neill, G. G., Sideras-Haddad, E., Singh, B., Steyn, G. F., Swartz, J. A., Usman, I. T., van Zyl, J. J.

Knowledge of the low-lying monopole strength in $\mathrm{^{12}C}$, the Hoyle state in particular, is crucial for our understanding of both the astrophysically important $3\alpha$ reaction and of $\alpha$-particle clustering. The $\mathrm{^{12}C}(\alp

The electron spectrometer, SPEDE, has been developed and will be employed in conjunction with the Miniball spectrometer at the HIE-ISOLDE facility, CERN. SPEDE allows for direct measurement of internal conversion electrons emitted in-flight, without
