Tidskriftsartikel (refereegranskat)abstract
- With the PROMICE/WASA detector setup at CELSIUS the reaction pp --> NN pi pi has been measured in the energy range from 650 to 775 MeV. These data constitute the first exclusive high-statistics measurements on a pure hydrogen target, supplying both differ

Tidskriftsartikel (refereegranskat)abstract
- A detector setup for the cooler storage ring CELSIUS is described. The setup detects particles produced in interactions between the internal beam and a cluster-jet target. Particles emitted in the forward direction are measured by means of arrays of plast

Tidskriftsartikel (refereegranskat)abstract
- The quasifree p + n --> d + eta reaction cross section has been measured in the near-threshold region using deuterium from an internal cluster-jet target and 1350 MeV protons in the CELSIUS storage ring of the The Svedberg Laboratory, Uppsala. The energy

Tidskriftsartikel (refereegranskat)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

Tidskriftsartikel (refereegranskat)abstract
- The quasifree p + n --> d + eta reaction cross section has been measured at the threshold using 1295 MeV protons in the CELSIUS storage ring and an internal cluster-jet deuterium target. The kinematics is chosen such that the target proton can be assumed

-
Tidskriftsartikel (refereegranskat)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 -->

Tidskriftsartikel (refereegranskat)abstract
- Kinematically complete events have been studied for the reactions dp-->dp pi (0) and dp-->dn pi (+) at projectile energies between 437 and 559 MeV. The measurement covers a range of pion momenta eta =p(pi ,c.m.)(max)/m(pi)c from near the production thresh
