Abstract

The present paper identifies unique symmetry properties of the d+dd+p+n breakup reaction that make it an excellent probe for studying charge-symmetry breaking. Measurements were made for two configurations of the ejected particles in the breakup reaction to obtain values of the spin observables Ay, Ayy, and Azz. These observables are compared for the mirror reactions H2(d,dp)n and H2(d,dn)p for the two angle pairs (d,d,N,N)=(17.0°,0°,17.0°, 180°) and (17.0°,0°,34.5°,180°) for an incident deutron energy of 12 MeV. In addition, spin observables for the H2(d,pn)d reaction at p=n and p=n+180°are shown to provide a particularly good test of charge symmetry. Our Ay, Ayy, and Azz data for the H2(d,pn)d reaction at (p,p,n,n)=(17.0°,0°,17.0°,180°) are used to illustrate this latter point. Of the ten charge-symmetric sets of observables measured, two were found to differ by 2.5 standard deviations.
