We present a method to determine precisely the absolute momentum of the external proton beam from the Julich Cooler Synchrotron COSY near 1930 MeV /c . In the pp → d π + reaction at 1930.477 MeV /c incident beam momentum, the forward going pions (

The motivation for the experiment is shortly discussed. In contrast to the classical method of π− absorption we will produce a π− directly in a bound state employing the COSY Julich proton beam. A special choice of the underlying kinematics fav

A comparison of nucleon-removal differential scattering cross sections at 35/sup 0/ for 190-MeV ..pi../sup + -/ on /sup 27/Al shows p2n removal and single-nucleon removal as the most dominant. Single-nucleon removal is consistent and in good agreemen
