Tidskriftsartikel (refereegranskat)abstract
- Using the simple relation between the np scattering and bound state wave functions, the spin-triplet contributions to the pp --> pi(+)(pn) and backward dp --> p(pn) reactions are estimated for low np excitation energies. The good agreement with the pion p

Ingår i: NUCLEAR PHYSICS A. - : ELSEVIER SCIENCE BV. - 0375-9474. ; 604:4, s. 441-454
-
Tidskriftsartikel (refereegranskat)abstract
- It is shown that in the impulse approximation the ratio of the near-threshold np --> {np}(I=0) eta to np --> d eta production rates depends weakly upon the form of the production operator and can be estimated using low-energy neutron-proton dynamics. The

Bound and unbound wave functions at short distances

Ingår i: AMERICAN JOURNAL OF PHYSICS. - : AMER INST PHYSICS. - 0002-9505. ; 66:10, s. 876-881
-
Tidskriftsartikel (refereegranskat)abstract
- There exists a simple relationship between a quantum-mechanical bound-state wave function and that of nearby scattering states, when the scattering energy is extrapolated to that of the bound state. This relationship is demonstrated numerically for the ca

Bound state and continuum production in large momentum transfer reactions

-
Tidskriftsartikel (refereegranskat)abstract
- The cross sections for pp --> pn pi(+) and pd --> pd pi(0) are related to those for the corresponding reactions producing bound deuterons and He-3's respectively. The large momentum transfers in the reactions involve short range operators and under these

Tidskriftsartikel (refereegranskat)abstract
- The pp --> pp eta and pp --> p Lambda K+ reactions near threshold are dominated by the first and second S-11 resonance respectively. It is shown that a one-pion-exchange model exciting these isobars reproduces well the ratio of the production cross sectio

Tidskriftsartikel (refereegranskat)abstract
- The normalization relation between the bound and scattering S-state wave functions, extrapolated to the bound state pole, is derived from the Schrodinger equation. It is shown that, unlike previous work, the result does not depend on the details of the po

Tidskriftsartikel (refereegranskat)abstract
- The cross section and deuteron tenser analysing power of the reaction pd-->He-3 eta are studied near threshold in a two-step model, where a pion beam, created in a NN-->d pi reaction on one of the nucleons in the target deuteron, is converted into an eta-
