Is there an isoscalar ''giant'' quadrupole resonance in /sup 12/C

· Phys. Rev. Lett.; (United States)
Apparent discrepancies in the amount of E2 strength located in the giant resonance region of /sup 12/C are resolved by a /sup 12/C(..cap alpha.., ..cap alpha..'c) coincidence experiment at 104 MeV. The summed E2 strengths in the dominant decay channels c = ..cap alpha../sub 0/,..cap alpha../sub 1/, and p/sub 0/ in the range 20 < or = E/sub x/ < or = 30 MeV exhaust less than 15% of the energy-weighted sum rule. So far /sup 12/C is the only investigated nucleus which does not exhibit a giant quadrupole resonance.
