${}^6$He + $\alpha$ clustering in ${}^{10}$Be

Abstract

In a kinematically complete measurement of the ${}^7$Li(${}^7$Li,$\alpha$${}^6$He)${}^4$He reaction at $E_i$ = 8 MeV it was observed that the ${}^{10}$Be excited states at 9.6 and 10.2 MeV decay by ${}^6$He emission. The state at 10.2 MeV may be a member of a rotational band based on the 6.18 MeV 0${}^{+}$ state.
