Measurements of proton beam flux and energy of APEP using foil activation technique

Nuclear Engineering and Technology
The activation method of metallic foils is an important technique to measure the flux and energy of proton beams. In this paper, the method was used to measure the CSNS APEP proton flux at seven nominal proton energies ranging from 10 MeV to 70 MeV for ...

Spin–phonon couplings in transition metal complexes with slow magnetic relaxation

Nature Communications, 2018
Transition metal complexes that display slow magnetic relaxation show promise for information storage, but our mechanistic understanding of the magnetic relaxation of such compounds remains limited. Here, the authors spectroscopically and computationally
