Dissociative Single Capture in p+HD Collisions

The few-body problem is a key issue in modern physics, describing the inability to predict the behavior of more than two mutually interacting particles. Even if the underlying forces are completely understood, the Schrödinger equation is not solvable. In order to approach this problem, theory must rely on models that need to be tested experimentally. The dynamics of a few-body system was analyzed by inducing single electron capture in a proton and hydrogen deuteride collision. A hot cathode source generated protons which were accelerated at the speed of 75 KeV. The accelerated proton beam crossed a cold target jet of Hydrogen Deuteride(HD) and induced collision events. Using position sensitive particle detectors the complete kinematic information of each collision event was recorded. Data analysis is still ongoing, but we have a preliminary date to present at the moment for the fully differential cross section for the single capture.. To the best of our knowledge, a fully-differential cross section of p+HD collision in the intermediate projectile energy regime has never before been reported and will provide valuable insight into few-body dynamics.
