Charge-Changing Particle-Hole Excitations and the pnTDA
- 1.6k Downloads
In this chapter we extend the Tamm-Dancoff approximation (TDA) to charge-changing particle-hole excitations. Such excitations consist of a proton particle and a neutron hole, or a neutron particle and a proton hole. These excitations of the doubly magic Hartree-Fock vacuum are nuclear states in the adjacent odd-odd nuclei. This formalism is well suited to describe beta-decay transitions from the states of one of the odd-odd nuclei to the ground and excited states of the even-even reference nucleus.
