On the 5.16 MeV and 7.56 MeV states of B10
Nuclear Physics, 1961The methods developed by Talmi and co-workers are used to calculate the binding energies of the two B10 levels formed by coupling 2s122 to the Be8 ground state. The calculated energies are found to be in excellent agreement with those of the B10 5.16 and 7.65 MeV levels for which the most probable spin-parity and isobaric-spin assignments are Jπ = 1 ...

An 80-Mev Model of a 300-Mev Betatron
Review of Scientific Instruments, 1950The construction and operation of a flux-biased 80-Mev betatron is described. This betatron was built as a model to test design features later to be incorporated in a 300-Mev betatron. Particular attention is paid to factors influencing design and to considerations of magnetic problems which are common to betatrons and synchrotrons such as the ...

The widths of the 9.991-MeV and 10.165-MeV levels in 27Al
Annals of Physics, 1968Abstract Gamma radiation from the decay of two resonances in the reaction 26Mg(p, γ)27Al at Ep = 1.785 MeV and 1.965-MeV, have been resonantly absorbed in aluminium to excite the states at 9.991 MeV and 10.165 MeV, respectively. In addition the γ-decay of the resonances have been studied in detail and angular distribution and yield measurements of ...

Nature, 1948
DURING the past few weeks, a betatron which has been under construction by the British Thomson-Houston Co., Ltd., has come into operation, and we give some preliminary account of its properties. The magnet and coil arrangement is shown in Fig. 1. The main features of the machine are :

Tracks in Metals by MeV Fullerenes
Physical Review Letters, 1995It is shown that new specific effects take place during irradiation of metals with high energy fullerene beams. The observed quasicontinuous damage is confined inside \ensuremath{\sim}20 nm diam cylinders around the projectile paths and is compared to the damage resulting from GeV heavy ion irradiation.

Nuclear excitation by 1 MeV to 3 MeV electrons
Nuclear Physics, 1965Abstract A calculation by Robl of the cross-section for nuclear excitation by low-energy electrons has been tested for states with measured lifetimes in Li7, In115 and Cd111. The inelastic electron scattering cross-section for 3 MeV electrons agrees with theory for the 0.478 MeV states of Li7. The total cross-sections for electron excitation of In115

Lifetimes of the 5.10 MeV and 5.83 MeV levels in 14N
Physics Letters, 1966Abstract The mean lifetimes of the 5.10 MeV and 5.83 MeV levels of 14N are 12.4 ± 1.4 ps and 18 ± 2 ps, respectively, as determined by a recoil-distance method. Absolute strengths are given for the dipole, quadrupole and octupole transitions for the γ decay of these levels.

Photodisintegration of the deuteron between 100 MeV and 320 MeV
Journal of Physics A: General Physics, 1968The photodisintegration of the deuteron has been studied for photon laboratory energies from 100 MeV to 320 MeV. Recoil protons were detected in a counter telescope and the effects of more complex reactions investigated by varying the bremsstrahlung end-point energy.

The spin assignments of the 9.16-MeV and 6.44-MeV states in N14
Nuclear Physics, 1959Abstract A study has been made of the gamma-ray cascade emitted by the 9.16-MeV state to the 6.44-MeV state and from this to the ground state of N14, using the reaction C13(p,γ)N14 at the 1.75 MeV resonance. By means of angular correlation and distribution measurements, using different geometrical arrangements relative to the beam, the 9.16-MeV state

Cluster ion–solid interactions from meV to MeV energies
Applied Physics A, 2008The nature of cluster ion–surface interactions changes dramatically with the kinetic energy and mass of the incoming cluster species. In this article we review some recent work on the nature of cluster–surface interactions spanning an energy range from a few tens of meV/atom to several MeV/cluster and cluster sizes in the range of 1–300000 atoms ...
