The design and performance of a high-resolution, broad range magnetic spectrograph are described. The angle of entry at the pole edge is chosen to give second order focussing, so the recorded line width is almost entirely due to the width of the obje

Two types of nuclear plate camera used for measurement of proton energies emitted from a toroidal discharge in deuterium in SCEPTRE are discussed. One of these records energies of protons emitted normal to the discharge axis, while the other records

Position-sensitive solid-state detectors have been used in double-scattering experiments with solid targets. Particles with second scattering angles θ 1ab from 36° to 144° were observed simultaneously by two of these detectors. Left-right asymmetr

Thin Cl37 targets were bombarded with monoenergetic protons, the overall proton energy resolution being about 1.7 keV. A long counter was used to observe neutrons from the Cl37(p, n)A37 reaction at energies up to 0.8 MeV above the reaction threshold.

Cross sections for the elastic scattering of protons by He4 have been measured for proton energies in the range 2⪅ Ep ⪅ 11 MeV (lab system), using a tandem Van de Graaff accelerator and a differentially-pumped gas scattering chamber. Excitation f

Absolute differential cross sections as a function of angle for the elastic scattering of protons by 12 C, and for the reactions which occur, were measured at incident proton energies E p = 2.39, 2.97, 3.97, 4.99, 5.66, 6.18, 6.65, 6.77, 8.07, 8.39,

Thin targets of natural argon gas were bombarded with protons with energies between 0.8 and 3.5 MeV. Differential cross sections were measured at three angles for elastic scattering and for the reactions A40(p, p′ γ)A40 and A40(p, α)Cl37. Many an

The scattering of protons from carbon in the range of incident energies 4.7 to 12.8 MeV has been investigated using a tandem Van de Graaff accelerator and a differentially pumped gas scattering chamber. Absolute differential cross sections for elasti
