Popis: We discuss two topics about the cluster structure in light neutron-rich nuclei with the astrophysical interests. One is 9Be: using a microscopic a + a + n model, the photodisintegration cross section is analyzed. It is shown that good agreement is achieved with the recently measured B(El) transition probability from the ground 3 2 − state to the first excited state ( 1 2 + ), which is 2 times larger than the previous measurement. The other topic is the cluster-shell mixing in 12C, which is crucial to explain the B(E2) value from the second 0+ state to the first. 2+ state in triple-α reaction.
