ON THE HINDRANCE OF 3(-) EXCITATIONS INDUCED BY NUCLEAR-SCATTERING

It has been reported that the excitation of low-lying 3(-) states in n uclei by hadronic probes indicate much weaker transition strengths tha n are implied by the results of electromagnetic measurements. We demon strate that this is a consequence of using the deformed optical potent ial model to analyze the hadronic scattering. The apparent hindrance d isappears when a folding model is used. The discrepancy between the re sults of using the two models increases dramatically as the multipolar ity of the transition increases, and we recommend the folding approach .
