It is true that the neutrino manifests itself in connection with particle energies far below those concerned in cosmic-rays, energies comparable with a million electron volts. It is to be observed, however, that there is nothing to require that / should change monotonically with increase of the velocity of the particle.It must further be pointed out that there is little to necessitate regarding the ordinary expression (3) as having anything to do with the quantity which we speak of in energy transitions in atomic structure problems. The assignment of energy levels in atoms, and the subsequent determination of frequencies by their differences,The following disintegrations have been studied in the range of deuteron energy from 100 to 250 kv: 3 Li 7 +iH2-> 2 He 4

A radial sector FFAG accelerator has been constructed and successfully operated. In this 8-sector accelerator electrons are betatron accelerated from 25 to 400 kev using both continuous and pulsed injection. The number of radial betatron oscillations per revolution may be varied from 2.3 to 3 and the number of vertical oscillations per revolution from 1 to 3. Calculations of these oscillation frequencies using various approximations are described and discussed. These frequencies have been measured statically with the unaccelerated beam and dynamically using an rf perturbing voltage on the accelerated beam. Results of these calculations and experiments are in satisfactory agreement. Effects of misalignments have been measured and are in close agreement with calculations presented. A survey has been made over a large area of the betatron oscillation stability region. The effects of the many resonances observed are in good qualitative agreement with theory.
