Plastic scintillators with 1-phenyl-3-(mesityl)-2-pyrazoline as unique fluorophore for efficient neutron/gamma pulse shape discrimination

Pulse-shape discrimination with PbWO4 crystal scintillators

The light output, α/β ratio, and pulse shape have been investigated at −25◦ C with PbWO4 crystal scintillators undoped, and doped by F, Eu, Mo, Gd and S. The fast 0.01 − 0.06 μs and middle 0.1 − 0.5 μs components of scintillation decay were observed for all the samples. Slow components of scintillation signal with the decay times 1− 3 μs and 13− 28 μs with the total intensity up to ≈ 50% have b...

Pulse-shape discrimination of La halide scintillators

The bright scintillators LaCl3:Ce and LaBr3:Ce were tested for a–g pulse-shape discrimination (PSD). PSD is demonstrated for LaCl3:Ce but not for LaBr3:Ce: r 2005 Elsevier B.V. All rights reserved.

Time Correlated Measurements Using Plastic Scintillators with Neutron-Photon Pulse Shape Discrimination

1-(1,3-Benzothia­zol-2-yl)-3-phenyl-2-pyrazoline

In the title compound, C(16)H(13)N(3)S, the pyrazoline ring forms dihedral angles of 6.89 (14) and 4.96 (11)° with the benzene ring and the benzothia-zole group, respectively. In the crystal, weak C-H⋯N inter-actions link the mol-ecules into chains extending along the b-axis direction.

1-Acetyl-5-ferrocenyl-3-phenyl-2-pyrazoline

In the title compound, [Fe(C(5)H(5))(C(16)H(15)N(2)O)], the pyrazoline ring and the phenyl ring are nearly coplanar, making a dihedral angle of 6.54 (2)°, while the substituted cyclo-penta-dienyl ring is twisted out of the pyrazoline ring plane by 81.32 (1)°. The mol-ecules in the crystal structure are held together by weak C-H⋯O inter-molecular hydrogen bonds and two C-H⋯π inter-actions.
