Abstract
An in-beam experiment with the subcoulomb reaction ²⁰⁹Bi(³He, d $^{*}\gamma\gamma$ )²¹⁰Po at 20.5 MeV was performed with two EUROBALL CLUSTER detectors in Cologne. It closed the gap between the low energy levels of the level-scheme and the high energy levels found in ²⁰⁹Bi(³He, d)²¹⁰Po and ²⁰⁸Pb(⁴He, t)²¹⁰Po particle experiments. New branchings have been found and the (³He, d $^{*}\gamma\gamma$ ) reaction below the coulomb-barrier has been used successfully.
