The 12C + α reaction rate from the elastic 16O breakup (original) (raw)

Evidence for direct elastic breakup of 160 into the c~-12C continuum with relative energies ranging from 900 to 1800 keV has been obtained in the scattering of 1527 MeV 160 projectiles off 2°8pb. An interpretation of E2 breakup including nuclear and Coulomb contributions leads to reduced electromagnetic transitions probabilities and astrophysical SE2 factors in reasonable agreement with direct measurements, showing that the method can be applied to extract the E2 part of the 12C(a, 3,) reaction rate. 0375-9474/97/$17.00 © 1997 -Elsevier Science B.V.
