Description

We would like to present the effect of including two-particle two-hole (2p-2h) states in nuclear resonances. Configuration spaces of 2p-2h are known to be important to describe a spreading width of nuclear resonances. Recently, our group pointed out that its effect is also important to reproduce high-energy particle emission rates. To understand this phenomena comprehensively, it is necessary to study the evolution from one-particle one-hole states to 2p-2h states. Some of new insight obtained by our recent investigation will be discussed in this talk.
