摘要: The energy spectrum of $^{14}\mathrm{C}$ ions emitted from $^{223}\mathrm{Ra}$ sources implanted at ISOLDE has been measured with the spectrometer SOLENO. highest statistics (899 events) and best resolution (90 keV) obtained so far in cluster decay allow a real spectroscopic study. Hindrance factors for transitions to ground state first excited $^{209}\mathrm{Pb}$, limits next three low-lying states, hae determined. data can be explained by parent wave function containing mainly ${\mathit{i}}_{11/2}$ spherical component.
