Quenching of single-particle strength from direct reactions with stable and rare-isotope beams

TL;DR

This review summarizes the current understanding of how direct nuclear reactions reveal nuclear structure, focusing on spectroscopic strength quenching and the effects of proton-neutron asymmetry in various reaction types.

Contribution

It provides a comprehensive overview of experimental techniques and insights into the quenching phenomena in nuclear reactions involving stable and rare-isotope beams.

Findings

Spectroscopic strength is quenched in direct reactions.

Proton-to-neutron asymmetry influences quenching effects.

Different reaction types provide complementary nuclear structure information.

Abstract

In this review article we discuss the present status of direct nuclear reactions and the nuclear structure aspects one can study with them. We discuss the spectroscopic information we can assess in experiments involving transfer reactions, heavy-ion-induced knockout reactions and quasifree scattering with (p,2p), (p,pn), and (e,e'p) reactions. In particular, we focus on the proton-to-neutron asymmetry of the quenching of the spectroscopic strength.
