Abstract
The E0 and E2 pair transitions from the Hoyle state have been measured, with the aim of deducing the radiative width and 3 alpha reaction rate by a new approach. The 3 alpha process is the only way carbon is synthesised in stars and is a bottleneck in stellar nucleosynthesis. The new method, which requires the ratio of the pair transitions, is expected to reduce the uncertainty from 10% to 5%. We recently observed the E2 pair transition for the first time, confirming the feasibility of the method. However, more statistics are needed to obtain a precise value for the radiative width.
