Differential cross section measurement for the d(n,np) reaction
The differential cross section for the quasielastic d(n,np) neutron-induced deuteron breakup reaction was measured as a function of incident and scattered particle energies and angles, using a liquid deuterium target at the Weapons Neutron Research (WNR) spallation neutron beam at the Los Alamos …

Cross Section Measurement of Exclusive ϕ-Meson Electroproduction off the Proton at CLAS12
… 1.97 ≤ W ≤ 4.03 GeV, and 0.17 ≤ −t ≤ 7.26GeV². Cross section σ(Q²,W) and differential cross section dσ/dt (Q²,W,t) measurements are reported. The scaling of the overall cross section was determined to be 1/Q⁶˙⁴⁷⁺⁻⁰˙⁹⁷, which is consistent with the Generalized Parton Distribution (GPD) prediction …
