This paper presents new data on the differential and integralγ-ray emission cross sections for Ga, Ge, Se, Sr, Y, Zr, Nb, and Mo irradiated with 14.1 MeV neutrons. The measurements were performed within the framework of the TANGRA (TAgged Neutrons and Gamma-RAys) project. A distinctive feature of this work was the use of the position-sensitive tagged neutron method (associated particle detection technique), implemented with a 9- pixel *a-particle detector built into the neutron generator. This approach enabled the identification of events corresponding to *g-ray emission directly from the sample based on time-of-flight, as well as the determination of the total number of neutrons that hit the sample without the need for additional neutron beam monitors. The detection system consisted of four LaBr&sub(3)(Ce) and two HPGe detectors, positioned at various angles relative to the axis of the central tagged neutron beam. Differential cross sections were obtained over an angular range of 23&sup(O)–85&sup(o) and subsequently expanded into even‑order Legendre polynomials to derive the integral cross sections
