Properties of resonances in 12C above the triple-alpha threshold

A complete kinematics study of the 10B(3He,pααα) and the 11B(3He,dααα) reactions has been performed to study the multi-particle break-up of 12C resonances above the triple-alpha threshold. The values of energy and widths of some states has been improved, and in states of natural parity partial branc...

Description
Summary:A complete kinematics study of the 10B(3He,pααα) and the 11B(3He,dααα) reactions has been performed to study the multi-particle break-up of 12C resonances above the triple-alpha threshold. The values of energy and widths of some states has been improved, and in states of natural parity partial branches of decay through the ground state of 8Be have been extracted. The influence of the "ghost" of the 8Be ground state has been taken into account in order to clarify the partial branches.
