The final results of some measurements on angular distribution and on Bremsstrahlung spectrum of the γ-ray beam of the Frascati electronsynchrotron are given. The experimental results of angular distribution for thick target fit with Schiff’s theo

A time-of-flight fast neutron spectrometer for continuous beams of neutron is described. The spectrometer utilizes the isochronous principle that monoenergetic neutrons scattered from a hydrogenous medium arrive at a suitably oriented spherical surfa

Simultaneous γ-ray and neutron excitation functions were measured for the bombardment of 14 C with 2.3 to 2.6 MeV protons to identify a 15 N level at E p = 2.452 MeV ( E x = 12.50 MeV, Γ = 44 keV) that is observed by neutron decay and a level at E

Three midget resonances in the 13C(p, γ)14N reaction were observed at Ep = 1012±2 keV, 1523±2 keV and 1701±1 keV corresponding to 14N excitation energies of 8.489, 8.963 and 9.129 MeV, respectively. The 8.489 MeV state decays by γ-ray emission p

A measurement of the γ-ray branching of the levels at 6.35, 6.90 and 7.50 MeV in C11 is described. The states of C11 were populated by the reaction Be9(He3,n)C11∗ and the resulting de-excitation γ-rays studied. Time-of-flight techniques were used

Efficiencies of a 50 cm 3 coaxial Ge(Li) detector have been determined for γ rays from 122 keV to 9.17 MeV for a source to detector distance of 10 cm. Measurements were made with radioactive sources for γ-rays energies up 3.25 MeV and with γ rays

An attempt was made to verify the reported existence of anomalies in elastic scattering of protons off 9 Be near the (p, n) threshold at 2.06 MeV. No such anomalies could be observed.

Coulomb excitation is investigated in the reaction Na/sup 23/(p,p' gamma )Na/sup 23/. The competition of resonance inelastic scattering complicates the unambiguous identity of Coulomb excitation in the light-mass region. The 874- kev resonance in thi

A pair spectrometer, having the capacity of analyzing photon energies up to 2 GeV is described. The optical properties of the instrument are examined by calculating the horizontal and vertical deviation matrices. Further, the magnetic measurements th
