The photofission cross section of [sup 232]Th was measured in the energy range 250--1200 MeV using a monochromatic tagged photon beam and a parallel-plate avalanche detector. The [sup 232]Th nuclear photofissility was obtained by measuring simultaneo

We present the results of the photofission cross section for 238 U measured between 200 and 1200 MeV. In the ‡ region our results agree with existing data on the total photoabsorption cross section, while at higher energy they show no evidence of t

For heavy nuclei, the sum of all the partial photoneutron cross-sections gives a reasonable approximation of the total photonuclear cross-section. Such partial photoneutron cross-sections were measured at Saclay with quasi monochromatic photons produ

A beam of 20–130 MeV positrons, with average intensities between 10 nA and 50 nA, is used at the 600 MeV Saclay Linac to create a quasi-monochromatic photon beam with a continuously variable energy. This beam was used to measure photoneutron cross

By using a variable monochromatic photon beam, the partial photoneutron cross sections σ(γ, n) + σ(γ, pn), σ(γ, 2n) and σ(γ, 3n) are determined in the region of the giant dipole resonance for the doubly even Mo isotopes 92 Mo, 94 Mo, 96 Mo, 9

The total photonuclear absorption cross section for Sn, Ce, Ta, Pb and U has been studied from 25 to 140 MeV using a continuously variable monochromatic photon beam obtained from the annihilation in flight of monoenergetic positrons. The basic experi

From event-by-event records of observed photoneutron multiplicities for photons from 30 to 140 MeV on several heavy targets (Sn, Ce, Ta and Pb), it was possible to determine the mean number of photoneutrons, \ gn, for each photon energy and the width

Partial photoneutron cross sections [σ(γ, n) + σ(γ, pn)] and σ(γ, 2n) of s-d shell nuclei were measured in the GDR region by means of a continuously variable monochromatic photon beam and a high efficiency neutron detecting system. In some case
