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
( ) at extreme forward angles and at =90° c.m. and the spin-correlation coefficientA
zx
( ) 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. |
