Excited states of the neutron-rich isotopes

{}_{42, 44}S

and

{}_{41, 43}P

have been investigated via inverse-kinematics proton scattering from a liquid hydrogen target, using the GRETINA

γ

-ray tracking array to extract inelastic-scattering cross sections. Deformation lengths of the

2_{1}^{+}

excitations in

{}_{42, 44}S

have been observed and, when combined with deformation lengths determined with electromagnetic probes, yield the ratio of neutron-to-proton matrix elements

M_{n} / M_{p}

for the

2_{1}^{+}

excitations in these nuclei. The present results for

{}_{41, 43}P (p, p^{'})

are used to compare two shell-model interactions, SDPF-U and SDPF-MU. As in a recent study of

{}_{42}{Si}

, the present results on

{}_{41, 43}P

favor the SDPF-MU interaction.
