Abstract

The sensitivity of neutron-proton scattering observables to the recently reported charge-independence breaking of the isospinT=13 P nucleon-nucleon interaction has been calculated. It is shown that only the analyzing powerA y (θ) at extreme forward angles and at θ=90° c.m. and the spin-correlation coefficientA zx (θ) at 90° c.m. exhibit a measurable sensitivity. It is concluded that the determination ofA y at 90° c.m. is currently the most accurate approach to verify independently charge-independence breaking in the3 P nucleon-nucleon phase shifts, considering the status of present experimental techniques.
