Description
The 14C(p,t)12C reaction was employed to investigate the much-discussed excitation energy region above the Hoyle state: there is evidence that suggests that in addition to the broad 0+ state at 10.3 MeV, an additional 0+ resonance is required at ~8.7 MeV. AMD calculations suggest that the Isoscalar Giant Monopole Resonance (ISGMR) may contribute to this region and suggest two distinct oscillation modes may play a role. The development of a new multi-channel R-matrix fitting programme aims to provide new insight by simultaneously analysing low-energy resonance data from multiple experiments (with different reaction channels). Moreover, a multi-channel two-level approximation is implemented which may help determine the contribution to this region from the ghost of the Hoyle state and any associated coherent interferences with other 0+ states.
