We have analyzed 2560 events in the final-state K O 1 K O 1 n produced in π − p interactions at 5, 7 and 12 GeV/ c . We observe the S ∗ (1070), f O and A 2 decaying into K O 1 K O 1 . Resonance parameters, cross sections, and branching ratios are given.

Two groups of measurements have been made on the elastic scattering of electrons by deuterium; in each case we observed the recoil deuteron instead of the scattered electron. In the first case the spectrometer was set at 45° so that magnetic scattering was unimportant (about 10%) and we deduced the electric form factors of the deuteron. In the second case deuterons were observed at 0°, allowing us to measure directly the magnetic form factor of the deuteron. Form factors of the neutron were deduced from these measurements for the transfer values q2=3, 4, and 5 (F−2). Preliminary results were given in a first paper. Here we also include a description of the experimental setup and discuss relativistic and exchange-current corrections.

We present results on elastic electron-deuteron experiments performed at Orsay. The range of momentum transfers is 0.6 to 2 F−2. Two kinds of measurements have been taken detecting the scattered electron: one with a solid CD2 target, the other with a liquid target. The data are analyzed with the nonrelativistic theory, which gives slightly positive neutron form factors and a magnetic neutron form factor nearly equal to the magnetic proton form factor.
