Abstract

The ¹³C + ⁹Be reactions have been measured using a ¹³C beam with an incident energy of 90MeV. The ¹⁷O excitation energy spectra have been reconstructed from the detected ¹³C + $\alpha$ coincidences. A number of the ¹⁷O states has been observed and their structure has been discussed in relation to the well-known ¹⁶O cluster states.
