A novel manifestation of $\alpha$-clustering: new '$\alpha$ + ${}^{208}$Pb' states in ${}^{212}$Po revealed by their enhanced E1 decays

A. Astier, P. Petkov, M. -G. Porquet +2

Excited states in ${}^{212}$Po were populated by $\alpha$ transfer using the ${}^{208}$Pb(${}^{18}$O, ${}^{14}$C) reaction and their deexcitation $\gamma$-rays were studied with the Euroball array.…
