Abstract

The robust (spin and isospin zero) α\alpha-particle remains one of the best projectiles to probe the nuclear isoscalar excitations. In the present work, a microscopic folding model analysis of the \ac inelastic scattering to the 2+^+ (4.44 MeV), 0+^+ (7.65 MeV), 3^- (9.64 MeV), 0+^+ (10.3 MeV) and 1^- (10.84 MeV) states in 12^{12}C has been performed using the 3-α\alpha resonating group method wave functions. The isoscalar transition strengths of these states were carefully studied based on the coupled-channel analysis using the microscopic folded form factors. A correlation between the weak binding and/or short lifetime of the excited state and absorption in the exit channel of inelastic scattering has been established.
