{alpha}+{sup 12}C inelastic angular distribution and nuclear size of {sup 12}C(0{sub 2}{sup +})

摘要: We analyze the inelastic scattering of \ensuremath{\alpha} particles on $^{12}\mathrm{C}$ exciting ${0}_{2}^{+}$ state at incident energies ${E}_{\ensuremath{\alpha}}=139\text{\ensuremath{-}}240$ MeV using \ensuremath{\alpha}-condensate model wave functions, and investigate effect nuclear radius $^{12}\mathrm{C}$(${0}_{2}^{+}$) angular distribution. It is found that oscillation pattern in distribution sensitive to extension transition density rather than excited state, although absolute value differential cross section $^{12}\mathrm{C}$(${0}_{2}^{+}$).
