Response to the He interpretation of MAMI's recent determination of H)
Ryoko Kino, Patrick Achenbach, Pascal Klag +5
We respond to the recent suggestion by A. Gal [arXiv:2604.18259] that the sharp pion-momentum peak at ~MeV/ observed in our $^7\mathrm{Li}(e,e^\prime K^+…
Precise measurement of the -binding energy difference between H and H via decay-pion spectroscopy at MAMI
Ryoko Kino, Sho Nagao, Patrick Achenbach +31
We performed high-precision decay-pion spectroscopy of light hypernuclei at the Mainz Microtron (MAMI) using the A1 spectrometer facility. By measuring the monochromatic $Ï^-…
Measurement of the helicity-dependent response in quasi-elastic proton knockout from
Tim Kolar, Iris Sabo-Napadensky, Patrick Achenbach +34
The role of the electron-helicity-dependent cross-section term and the structure function in the quasi-elastic process was studied. The…
Measurement of ground state energy in an electron scattering experiment at MAMI-A1
Tianhao Shao, Jinhui Chen, Josef Pochodzalla +28
For the first time the neutron-rich hydrogen isotope was produced in an electron scattering experiment in the reaction using the spectro…
Measurement of the Ar(e,e) elastic scattering cross section with a novel gas-jet target
M. Littich, L. Doria, P. Brand +35
We report on a measurement of elastic electron scattering on argon performed with a novel cryogenic gas-jet target at the Mainz Microtron accelerator MAMI. The luminosity is estima…
Nuclear density dependence of polarization transfer in quasi-elastic reactions
T. Kolar, W. Cosyn, C. Giusti +52
The ratio of the transverse and longitudinal component of polarization transfer to protons in the quasi-elastic reaction, $P^{\prime}_x/P^{\prime}…
