The differential cross section has been measured at 30, 50, 80, 100, 120 and 140 GeV/ c for 0.002 < | t | < 0.04 ( GeV / c ) 2 . The results show that the π − p real part goes from negative to positive values below 80 GeV/ c . The slope parameter in the t -region measured is significantly higher than what has been found − t = 0.2 (GeV/ c ) 2 .

We present data on the five final states Λω, Λφ, Λϱ 0 , Σ 0 ⊘ and Σ 0 ϱ 0 produced in 3.1–3.6 GeV/ c K − p interactions. These data are from a bubble chamber experiment with 18 events/μb. For all reactions the data consist of the overall and differetial cross sections, and the hyperon polarisation and the vector meson's density matrix elements as a function of momentum transfer. For Λω and Λ⊘, an almost complete amplitude analysis is performed in several regions of momentum transfer. The data are examined from the point of view of various exchange models.

We present differential cross sections for elastic p d scattering at beam momenta 0.735 and 0.940 GeV/ c and momentum transfers in the range 0.04<| t |<0.5(GeV/ c ) 2 . The p d elastic differential cross section is expressed in terms of a deutron form factor and the I =0 t -channel exchange N N amplitudes, enabling us to isolate the corresponding I =0 t -channel exchange cross sections.

The p p and p n elastic differential cross sections have been extracted from the reaction p d→ p pn in which the deuteron breaks up. The incident antiproton momenta were 0.480, 0.735 and 0.940 GeV/ c , and the range of the momentum transfers was 0.04 < ∣ t ∣ < 0.7 (GeV/ c ) 2 . Both p p and p n differential cross sections are diffraction-like, with structure similar to the higher-momentum data.
