In-Beam Spectroscopy Using the (t,p) Reaction

Abstract

Charged particle spectroscopy using the (t,p) reaction has been employed for more than two decades to study the low-energy structure of nuclei. This reaction has contributed significantly to the elucidation of single-particle and collective phenomena for neutron rich nuclei in virtually every mass region. We have begun to use the (t,p) reaction in conjunction with in-beam γ-ray and conversion-electron spectroscopy to bring additional understanding to low-energy nuclear structure. In this report we briefly discuss the experimental considerations in using this reaction for in-beam spectroscopy, and present some results for nuclei with mass near 100. EXPERIMENTAL METHODS Until now the only methods available for studying the beta unstable nuclei with a mass near 100 were the prompt γ-ray decay and beta decay of fission products, charged-particle spectroscopy using two-neutron transfer reactions, and, to a limited extent, in-beam spectroscopy using reactions like (18O,16Oγ). In-beam spectroscopy using the (t,pγ) reaction has several features
