Response to the $_{I^}^{7} $ He interpretation of MAMI's recent determination of $B_{I^} (_{I^}^{3} $ 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 $p_{I ¨ ^{-}} \approx 113.8$ ~MeV/ $c$ observed in our $^7\mathrm{Li}(e,e^\prime K^+…

Precise measurement of the $I^$ -binding energy difference between $_{I^}^{3} $ H and $_{I^}^{4} $ H via decay-pion spectroscopy at MAMI

Ryoko Kino, Sho Nagao, Patrick Achenbach +31

We performed high-precision decay-pion spectroscopy of light $I^$ hypernuclei at the Mainz Microtron (MAMI) using the A1 spectrometer facility. By measuring the monochromatic $Ï^-…

Measurement of $I^$ Polarization in the $I ¨ ^{-} p \to K^{0} I^$ Reaction at $p_{I ¨ ^{-}} = 1.33$ GeV/ $c$ toward a New $I^ p$ Scattering Experiment

PARC E40 Collaboration, T. Sakao, K. Miwa +69

This paper presents high-precision experimental data of the polarization of the $I^$ hyperon in the $I ¨ ^{-} p \to K^{0} I^$ reaction, measured in the angular range $0.6<\cos Î¸^{CM}…

Inclusive studies of two- and three-nucleon short-range correlations in $^{3}$ H and $^{3}$ He

S. Li, S. N. Santiesteban, J. Arrington +113

Inclusive electron scattering at carefully chosen kinematics can isolate scattering from the high-momentum nucleons in short-range correlations (SRCs). SRCs are produced by the har…

Measurement of $^{6} H$ 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 $^{6} H$ was produced in an electron scattering experiment in the reaction $^{7} Li (e, e^{'} p I ¨ ^{+})^{6} H$ using the spectro…
