Scattering of the halo nucleus 11Be from a lead target at 3.5 times the Coulomb barrier energy

Physics Letters B, 2020
Angular distributions of quasielastic scattering and breakup of the neutron-rich halo nucleus 11Be on a 208Pb target at an incident energy of 140 MeV (about 3.5 times the Coulomb barrier) were measured at HIRFL-RIBLL.

Hydrogen Dynamics in Hydrated Chitosan by Quasi-Elastic Neutron Scattering

Bioengineering, 2022
Chitosan, an environmentally friendly and highly bio-producible material, is a potential proton-conducting electrolyte for use in fuel cells. Thus, to microscopically elucidate proton transport in hydrated chitosan, we employed the quasi-elastic neutron ...

Achieving nanosecond time resolution with a two-dimensional X-ray detector. [PDF]

J Synchrotron Radiat
A proof‐of‐principle of a nanosecond time‐resolved experiment is demonstrated using a TEMPUS detector. The concept exploits an event driven mode of the detector and cross‐correlation analysis to overcome pixel dead time, and offers new opportunities for time‐resolved studies.The fastest pixel array X‐ray detectors can record images with nanosecond ...
