| The nuclei $^{12}$Be and $^{14}$Be have been investigated using breakup reactions on p, $^{12}$C and $^{208}$Pb targets. The decay of $^{12}$Be into two helium clusters ($^6$He+$^6$He and $^4$He+$^8$He) was observed from a series of excited states between 10 and 25 MeV with spins in the range 4 to 8h, consistent with a deformed “molecular” structure. In the case of $^{14}Be, narrow forward peaked single-neutron angular distributions were were observed for the breakup to $^{12}Be. Analysis of the associated neutron-neutron correlations indicate an RMS separation for the halo neutrons of around 5 fm. |
