TL;DR: In this paper, the mass of the η meson was determined for the p + d → 3 He + X reaction using a calibrated magnetic spectrograph, and the final result was m(η) = 547.311 ± 0.028(stat) ±0.032(syst) MeV/c 2.

TL;DR: In this paper, a stack of annular detectors made of high-purity germanium was used to measure simultaneously pd → 3H π + and pd→ 3He π 0 differential cross sections at beam momenta of 750, 800, and 850 MeV/c over a large angular range.

Measurement of 42 MeV 7Li projectile breakup on 208Pb target near grazing incidence
TL;DR: In this article, the authors studied the breakup of 42 MeV 7 Li projectiles in the field of a 208 Pb target near the grazing angle and found that the direct breakup contribution is dominant over the sequential breakup for the θ α > θ t set.

TL;DR: In this paper, the s-wave scattering amplitude from both the polarized and unpolarized d + d → 4He + η reaction at 2385.5 MeV/c allowed to determine the scattering length which fulfills the requirements for bound η.
