Photofission of 232Th near threshold

Nuclear Physics A, 1986
Abstract Measurements are presented of the photofission cross section and the mean number ν of neutrons per fission for 232 Th made using bremsstrahlung from the Harwell electron linear accelerator HELIOS and a high efficiency neutron detector to record neutron multiplicity distributions.

Fast neutron capture in 232Th

Journal of Inorganic and Nuclear Chemistry, 1963
The capture cross section of 232Th has been determined for monoenergetic neutrons in the energy range 0·19–1·1 MeV. The shape of the curve agrees closely with the theoretical curve predicted by Lane and Lynn,(1) showing a definite rise in cross section with increasing energy near 0·8 MeV.

Fission of muonic 232Th and 239Pu

Nuclear Physics A, 1978
Abstract The neutron emission is studied following the formation of muonic atoms of 232 Th and 239 Pu. Energy and time distributions are measured. Various processes which contribute to the measured spectra are considered. A collective resonance model of the muon capture is used to calculate the nuclear excitation function.

Coulomb excitation of states in 232Th

Nuclear Physics A, 1993
Abstract Twenty-five states in 232 Th have been observed with 18 MeV 4 He ions on a thick target. Eleven 2 + states between 774 and 1554 keV and three 3 − states are populated by direct E2 and E3, respectively. The remaining states are either weakly excited by multiple Coulomb excitation and/or populated by the decay of the directly excited ...

A comparison of the 232Th-235U and 232Th-233U PHWRs

Annals of Nuclear Energy, 1987
Abstract The performance of a PHWR loaded with a mixture of 232 Th, pure 235 U and a burnable poison was calculated. The obtained results were compared with those obtained for a second-generation 232 Th- 233 U PHWR. This comparison shows that the 232 Th- 235 U PHWR is still good enough to be recommended for use in place of the 232 Th- 233 U ...

Thorium concentration and the activity ratios230Th/232Th and228Th/232Th in sea water in the western North Pacific

Journal of Oceanography, 1970
The concentration of thorium isotopes and the activity ratios of230Th/232Th and228Th/232Th in sea water collected in the Kuroshio region, the mixing area of Oyashio and Kuroshio, the Japan Sea and the East China Sea in the western North Pacific were determined.

232Th fission barrier characteristics from the 232Th (p,p′f) reaction

1982
Fission fragments in coincidence with protons inelastically scattered from the region of the fission barrier in 232Th have been measured for several angles. With the high resolution of ≅ 17 keV at Ep = 30 MeV a detailed excitation function of fission probability was obtained.

Near-barrier fission of the system12C+232Th

Zeitschrift f�r Physik A Hadrons and Nuclei, 1995
The fission fragment angular distributions for the system12C +232Th have been measured in the energy range 0.97 1.05, they are abnormally large at lower energies. This is also true for the existing measurements of16O and19F +232Th systems. Since for this system pre-equilibrium fission contributions are not expected, this anomaly indicates strong ...

Photofission in238U,232Th and209Bi at intermediate energy

Zeitschrift f�r Physik A Atoms and Nuclei, 1977
Fragment energy correlation measurements have been made for238U,232Th and209Bi with bremsstrahlung of 600 MeV maximum energy. The study was performed with silicon surface barrier detectors. Distributions of kinetic energy as a function of fragment mass are presented.

Collective states of 232Th, 238U and 242Pu

Nuclear Physics A, 1972
Abstract Energy levels of 232 Th, 238 U and 242 Pu have been studied through inelastic scattering of 16 MeV deuterons. Inelastic scattering cross sections were measured at 90° and 125° by means of a magnetic spectrograph. In all three of the nuclei studied, the ground state rotational bands were excited up to the 8 + member.
