AI Article Synopsis
- The text discusses the introduction of a nuclear neutron-proton contact, building on previous work by Tan, and evaluates it using experiments related to nuclear photodisintegration.
- It reformulates the quasideuteron model to connect the Levinger constant with this neutron-proton contact, allowing for experimental values to be used for extraction.
- Lastly, it suggests that assuming isospin symmetry could enable the evaluation of neutron-neutron contact by measuring correlations in photonuclear spin between neutron-proton pairs.
Article Abstract
The nuclear neutron-proton contact is introduced, generalizing Tan's work, and evaluated from medium energy nuclear photodisintegration experiments. To this end we reformulate the quasideuteron model of nuclear photodisintegration and establish the bridge between the Levinger constant and the contact. Using experimental evaluations of Levinger's constant, we extract the value of the neutron-proton contact in finite nuclei and in symmetric nuclear matter. Assuming isospin symmetry we propose to evaluate the neutron-neutron contact through the measurement of photonuclear spin correlated neutron-proton pairs.

A neutron diagnostic for high current deuterium beams.

A neutron diagnostic for high current deuterium beams is proposed for installation on the spectral shear interferometry for direct electric field reconstruction (SPIDER, Source for Production of Ion of Deuterium Extracted from RF plasma) test beam facility. The proposed detection system is called Close-contact Neutron Emission Surface Mapping (CNESM). The diagnostic aims at providing the map of the neutron emission on the beam dump surface by placing a detector in close contact, right behind the dump.
