Two-nucleon momentum distributions measured in 3He(e,e'pp)n.

We have measured the 3He(e,e'pp)n reaction at 2.2 GeV over a wide kinematic range. The kinetic energy distribution for "fast" nucleons (p>250 MeV/c) peaks where two nucleons each have 20% or less, and the third nucleon has most of the transferred energy.

The growth of some mycobacteria on cultured human tissues.

M. ulcerans grows in close association with the surface of cultured human foetal and adult tissue and produces necrosis. M.
