Article Synopsis
  • The study focuses on measuring the x-ray transitions in kaonic ^{3}He and ^{4}He atoms using advanced microcalorimeters, achieving high energy resolution.
  • The measured transition energies are 6224.5 eV for kaonic ^{3}He and 6463.7 eV for kaonic ^{4}He, with significantly lower width values compared to earlier findings.
  • The results challenge previous theories suggesting large interaction shifts and align more closely with predictions made by optical-potential models.

A performance evaluation of superconducting transition-edge sensors (TESs) in the environment of a pion beam line at a particle accelerator is presented. Averaged across the 209 functioning sensors in the array, the achieved energy resolution is 5.2 eV FWHM at Co (6.

Evidence for the neutron-rich hypernucleus (Λ)(6)H is presented from the FINUDA experiment at DAΦNE, Frascati, studying (π+,π-) pairs in coincidence from the K(stop)(-) + (6)Li →(Λ)(6)H + π+ production reaction followed by (Λ)(6)H → (6)He + π- weak decay. The production rate of (Λ)(6) undergoing this two-body π- decay is determined to be (2.9 ± 2.

We performed a coincidence measurement of two nucleons emitted from the nonmesonic weak decay of lambda(5)He formed via the 6Li(pi+, K+) reaction. The energies of the two nucleons and the pair number distributions in the opening angle between them were measured. In both np and nn pairs, we observed a clean back-to-back correlation coming from the two-body weak reactions of lambda p --> np and lambda n --> nn, respectively.
