Measurements of the 30 keV isomer production cross-section in 93 Nb, excited by neutron inelastic scattering have been made at 10 neutron energies in the range 1–6 MeV. Small foils of niobium and suitable monitor elements were exposed to high fluen

The fission-neutron angular distributions have been measured relative to the incident beam in the photofission of 232Th and 238U near the fission threshold. The Harwell 45 MeV electron linac was used to provide bremsstrahlung with end-point energies

The relative shape of the 6Li(n,α)235U(n,f) cross-section ratio has been determined in the range of incident neutron energy from 2 to 800 keV. The measurements were made by the time-of-flight method using the Harwell 45 MeV linac to provide the puls

An analysis is made of the decays of 45 F0-particles associated with nuclear interactions in a lead plate mounted inside a cloud chamber. Data are given on the energy spectra of the Λ 0- and θ0-particles and possible sources of experimental bias ar

The neutron total cross-sections of several plutonium samples have been measured from 0·02 eV to 51 keV, using the Harwell fast chopper. The samples contained various abundances of 23Pu 240PU 241Pu and 242Pu, making it possible in most cases to assi

The time-of-flight method has been used to measure the energy spectra of neutrons emitted by targets of natural uranium, lead, bismuth and tungsten when bombarded by 45 MeV electrons from the Harwell linear accelerator. The spectra were measured at 9

A study is made of the properties of the decays of about 50 V 0-particles in a medium-sized cloud chamber equipped with either one or two lead plates but without a magnetic field. The decays are classified into those due to ϑ0- and to ∧0-particles

Gamma-ray spectra from the reactions 12 C(γ, nγ') and 12 C(γ, pγ') have been measured at 112° using bremsstrahlung photons with end-point energies 24.5, 27, 33 and 42 MeV in order to study the transitions from the giant dipole resonance in 12 C
