Exploring the 12C(e, e′π+ π+) and 12C(e, e′ p π+) reactions at the A1 multi-spectrometer facility at MAMI — •Philipp Eckert1, Toshiyuki Gogami2, Masashi Kaneta3, Sho Nagao3, Satoshi Nakamura3, and Yuichi Toyama3 — 1Johannes Gutenberg-Universität Mainz — 2Kyoto University — 3Tohoku University, Sendai
Within the past years the chart of observed nuclides was continuously extended to more extreme proton-to-neutron ratios. For a further high resolution study of especially neutron rich nuclei, a new experimental method via electron scattering was explored at the Mainz Mikrotron. This method includes the missing mass spectroscopy of the reactions 12C(e, e′π+ π+) and 12C(e, e′ p π+), where the three spectrometer facility of the A1 Collaboration and the precise MAMI beam energy would allow a yet unprecidented missing mass resolution of around 100 keV/c2.
We will present the results of a test experiment performed at MAMI.
