Nuclear microscopic structural models that treat two-body effective interactions self-consistently becomes available, one of which is second-random-phase-approximation (SRPA). SRPA can be used to study evolutions from 1 particle-1 hole (1p1h) to 2 particle-2 hole (2p2h) states from different points of view from reaction models. We studied nuclear excitations created by 1-body and 2-body external fields and discussed transitions between the 1p1h and 2p2h states obtained by the SRPA approach.
