“…[30], the event selection and acceptance correction being performed in a way similar to that described for 4 He. The numbers obtained from this analysis (317 nb −1 , 1425 nb −1 and 255 nb −1 at the three energies) are consistent with those determined from the dd → 4 He X data within the overall uncertainties.…”

Abstract. The dd → 4 He η reaction has been investigated near threshold using the ANKE facility at COSY-Jülich. Both total and differential cross sections have been measured at two excess energies, Q = 2.6 MeV and 7.7 MeV, with a subthreshold measurement being undertaken at Q = −2.6 MeV to study the physical background. While consistent with isotropy at the lower energy, the angular distribution reveals a pronounced anisotropy at the higher one, indicating the presence of higher partial waves. Options for the decomposition into partial amplitudes and their consequences for determination of the s-wave η-α scattering length are discussed.PACS. 13.60.Le meson production -25.10.+s nuclear reaction involving few-nucleons systems -25.45.-z 2 H induced reactions -11.80.Et partial-wave analysis

“…Here we introduce notation Ψ i jk ( P h , M h , τ h ) for the 3 He wave function, where 3 He is formed by i, j, k nucleons and has momentum P h , spin projection M h and isospin projection τ h . Note in case τ = −1/2 we deal with the reaction of dd → t p. The Ψ i j ( P, M) denotes the wave function of the deuteron with momentum P and spin projection M. In our calculation we use the parameterized wave functions both for a three-nucleon system ref.…”

“…The vector and tensor analyzing powers were obtained in a wide angular range at three deuteron kinetic energies: 140, 200, and 270 MeV. Previously the differential cross sections of the reactions 2 H(d, n) 3 He and 2 H(d, p) 3 H were measured for incident deuteron momenta between 1.1 GeV/c and 2.5 GeV/c [3].…”
