10. Polarisation of the ω meson in the pd→He3ω reaction at 1360 and 1450 MeV

Abstract

The tensor polarisation of ω mesons produced in the pd→He3ω reaction has been studied at two energies near threshold. The He3 nuclei were detected in coincidence with the π0π+π− or π0γ decay products of the ω. In contrast to the case of ϕ-meson production, the ω mesons are found to be unpolarised. This brings into question the applicability of the Okubo–Zweig–Iizuka rule when comparing the production of vector mesons in low energy hadronic reactions.

11. The pd→He3ηπ0 reaction at Tp=1450 MeV

Abstract

The cross section for the pd→He3ηπ0 reaction has been measured at a beam energy of 1450 MeV using the WASA detector at the CELSIUS storage ring. The 3He was detected in coincidence with four photons from the decays of the two mesons. The data indicate that the production mechanism involves the formation of the Δ(1232) isobar. Although the beam energy does not allow the full peak of this resonance to be seen, the invariant mass distributions of all three pairs of final particles are well reproduced by a phase space Monte Carlo simulation weighted with the p-wave factor of the square of the π0 momentum in the He3π0 system.

15. A new surface laboratory for measurements of low-level radioactivity

Subjects
*RADIOACTIVITY, *LABORATORIES, *GAMMA ray spectrometry, *CONSTRUCTION materials
Abstract

Abstract: A laboratory for measuring low-level radioactivity has been built at the AlbaNova University Center in Stockholm. Low-level concrete in combination with a 5cm iron lining provide an average photon fluency rate from terrestrial sources at least a factor of 40 below that in the common laboratories of the Center. The radon activity inside the laboratory has been measured to . Material considerations are discussed. Construction and performance of the laboratory, as well as the present instrumentation, is described. [Copyright &y& Elsevier]

16. Pionic fusion study of the 6He halo

Abstract

Abstract: The halo nucleus 6He has been studied in a pionic fusion experiment at the CELSIUS ring in Uppsala. The aim of the experiment was to investigate, in particular, the high-momentum part of the halo wave function by measuring the differential cross section for the 4He(d, 6He) reaction 0.6, 1.2 and 5.0 MeV above threshold in the centre-of-mass frame. The 6He ions were detected in a solid-state detector telescope inserted into the ring vacuum. The result for the total cross section is, respectively, 22(1), 38(1) and 57(9) nb with a common systematic uncertainty of . The differential cross section is clearly anisotropic: , and at the same three energies. The preferred direction of emission for the pion is parallel to the momentum of the 4He ion in the initial state. In terms of a simple model for the reaction the results depend sensitively on the state of motion of the centre of mass of the halo relative to that of the core. [Copyright &y& Elsevier]
