On the role of indirect processes in the inelastic excitation of low lying 0+ states

Isoscalar monopole and dipole transitions inMg24,Mg26, andSi

“…[7,23,24] for a general view and Refs. [25][26][27][28][29][30][31][33][34][35] ( 24 Mg), [30,[36][37][38][39][40][41][42]] ( 26 Mg), [31-33, 35, 40, 42-47] ( 28 Si) for particular studies). We now provide comparative experimental and theoretical analyses of these nuclei.…”

β-band excitation in inelastic hadron scattering and the mixing of the breathing mode into the low-lying β-vibrations

“…This failure could partly be attributed to strong coupled channel (CC) effects, since in the study of inelastic proton scattering from 24Mg at 0.8 GeV, Blanpied et al [12] concluded from a full CC analysis in the 0-vibrational model that the 0 + state at 6.43 MeV can not be described by a pure monopole/3-vibration form factor alone. CC effects on the excitation of the 0~ of 24Mg were studied earlier [13] using a wrong coupling scheme where the same form factor + was taken for the 0g s ~ 2 + and 2 + ~ 0/3 transitions but more importantly the 2~-state was omitted from the coupling scheme.…”
