Isoscalar monopole and quadrupole strength of /sup 16/O in an. cap alpha. +/sup 12/C cluster and symplectic mixed basis

Journal Article · · Phys. Rev. C; (United States)
;
The isoscalar monopole (E0) and quadrupole (E2) transition strength of /sup 16/O is used to study how well the ..cap alpha..+/sup 12/C cluster model works for explaining the strength distributions observed up to the isoscalar giant resonance region. The cluster model reproduces 54% of the E0 and 65% of the E2 energy weighted sum-rule strength. A symplectic basis, which naturally reproduces the sum rule, is mixed with the cluster basis to see how much of the missing strength is accounted for. A mixed basis calculation shows that the symplectic basis does not ruin the successful agreement of the cluster model with experiment obtained in the low-energy region and increases the strength by 30% for E0 and 20% for E2 below E/sub x/less than or equal to40 MeV. It is predicted that both of the E0 and E2 strengths are split into two peaks in the giant resonance region with a greater spread over the excitation energy than expected.
