Abstract

States of ${}^{208}{Po}$ up to an excitation energy of 2 MeV have been investigated via the two-neutron pickup reaction ${}^{210}{Po} (p, t) {}^{208}{Po}$ . We have extracted angular distributions for the five observed states of ${}^{208}{Po}$ and have made $J^{π}$ assignments. These states are discussed in terms of the excitation of simple modes observed in ${}^{206}{Pb}$ and ${}^{210}{Po}$ . Matrix elements have been extracted for the interaction between the two-neutron-hole $2^{+}$ excitations and the two-proton-particle $2^{+}$ excitations and compared with simple theoretical estimates.
