摘要：
We calculate the total cross sections for different multiple transitions in photon absorption in a 1S0 pp pair embedded in a He3 nucleus. Employing two models, one involving only nucleon degrees of freedom, the other in addition the Δ(1232) isobar, we show that the Δ gives important effects even in transitions where the photon cannot couple directly to the isobar. © 1995 The American Physical Society.
