  A study of the inelastic scattering of neutrons with an energy of $14.1$~MeV
on the nuclei of oxygen, phosphorus and sulfur was carried out at the TANGRA
facility at JINR (Dubna). The purpose of the experiment was to refine existing
and obtain new data on the yields and angular distributions of $\gamma$-quanta
emitted by the studied nuclei as a result of neutron-induced nuclear reactions
using the tagged neutron method. Two types of detector systems were used to
register $\gamma$-quanta. The $\gamma$-ray yields were measured using a
high-purity germanium (HPGe) detector. The angular distributions of
$\gamma$-rays were obtained using a system of 18 scintillation detectors based
on bismuth germanite Bi$_{4}$Ge$_{3}$O$_{12}$ (BGO) located around the sample.
As a result of the studies carried out, the yields of two transitions for the
reaction of tagged neutrons with $^{16}$O, nine transitions for the reaction
with $^{31}$P, and nine transitions for the reaction with $^{32}$S were
measured for the first time. The angular anisotropy of the $\gamma$-radiation
accompanying the inelastic scattering of neutrons with an energy of $14.1$~MeV
on $^{31}$P nuclei was also measured for the first time.
