Conference paper (peer-reviewed)abstract
- The quasi-free p+n-->d+eta reaction cross section has been measured at threshold using 1295 MeV protons in the CELSIUS storage ring and an internal cluster-jet deuterium target [1]. Excess energies from threshold to 10 MeV in the center of mass of the fin

Conference paper (peer-reviewed)abstract
- Two-pion production reactions in proton-proton collisions near threshold are measured using an internal cluster-jet hydrogen target and the WASA/PROMICE detector at the CELSIUS storage ring. Four out of the five possible two-pion production reactions are

Journal article (peer-reviewed)abstract
- The first measurement of the cross section of the quasifree pn-->pn eta reaction has been carried out at the CELSIUS storage ring using a deuterium internal cluster jet target. The energy dependence of the cross section is extracted using a fixed incident

Upper limits for a narrow dibaryon in pp collisions at 200 and 310 MeV

-
In: PHYSICS LETTERS B. - : ELSEVIER SCIENCE BV. - 0370-2693. ; 427:3-4, s. 248-253
-
Journal article (peer-reviewed)abstract
- Dibaryons, forbidden by mass to decay into NN pi channel and by quantum numbers into NN channel, may still have escaped detection. In fact, recently an observation of a narrow dibaryon (D) with the mass close to 1920 MeV was reported in the process pp -->

Conference paper (peer-reviewed)abstract
- The pp --> pp pi(o) and pn --> pp pi(-) reactions have been measured at 310, 320 and 340 MeV using the CELSIUS proton beam and H-1 and H-2 internal cluster-jet targets. The pi(o) production at 310 MeV has been fully analyzed and a significant deviation fr

Pionic d-wave effects in pp -> pp pi(0) near threshold

In: PHYSICS LETTERS B. - : ELSEVIER SCIENCE BV. - 0370-2693. ; 436:3-4, s. 251-256
-
Journal article (peer-reviewed)abstract
- The angular distribution of neutral pions produced in the pp --> pp pi(0) reaction has been measured at a beam energy of 310 MeV. Significant deviations from isotropy are found, which increase for small excitation energies of the final proton-proton pair.
