Anomalous Quenching ofS=1Two-Nucleon Transfer

Abstract
Examination of the ground-state transitions of the (p,t) and (p,He3) reactions on all Tz=12 nuclei from Ne21 through K39 reveals a systematic suppression of the S=1, T=0 component of the (p,He3) transfer cross sections which is not explained in terms of current structure and reaction theories.
