Positron annihilation and binding in aromatic and other ring molecules
E. Arthur-Baidoo, J. R. Danielson, C. M. Surko +6
Annihilation spectra are presented for aromatic and heterocyclic ring molecules resolved as a function of incident positron energy using a trap-based positron beam. Comparisons wit…
Measurement of the Neutron Cross Section on Argon Between 95 and 720 MeV
S. Martynenko, B. Bhandari, J. Bian +72
We report an extended measurement of the neutron cross section on argon in the energy range of 95-720 MeV. The measurement was obtained with a 4.3-hour exposure of the Mini-CAPTAIN…
Effect of chlorination on positron binding to hydrocarbons: experiment and theory
A. R. Swann, G. F. Gribakin, J. R. Danielson +3
Measured and calculated positron binding energies are presented for a range of hydrocarbons with up to six carbon atoms (viz., methane, acetylene, ethylene, ethane, propane, butane…
The Mini-CAPTAIN Liquid Argon Time Projection Chamber
CAPTAIN Collaboration, C. E. Taylor, B. Bhandari +73
This manuscript describes the commissioning of the Mini-CAPTAIN liquid argon detector in a neutron beam at the Los Alamos Neutron Science Center (LANSCE), which led to a first meas…
First Measurement of the Total Neutron Cross Section on Argon Between 100 and 800 MeV
B. Bhandari, J. Bian, K. Bilton +73
We report the first measurement of the neutron cross section on argon in the energy range of 100-800 MeV. The measurement was obtained with a 4.3-hour exposure of the Mini-CAPTAIN…
Mode coupling and multiquantum vibrational excitations in Feshbach-resonant positron annihilation in molecules
G. F. Gribakin, J. F. Stanton, J. R. Danielson +2
The dominant mechanism of low-energy positron annihilation in polyatomic molecules is through positron capture in vibrational Feshbach resonances (VFR). In this paper we investigat…
