Blanking Method for Continuous Channel Electron Multipliers
(The American Institute of Physics, 1970-10)
Field dependence of currents
(Elsevier, 1970-02-15)
Arguments are presented to show that in a theory with spin , vector and axial-vector fields, the vector current in general depends upon the axial-vector field also in addition to the dependence on the vector field. The ...
Coulomb excitation by 45 MeV alpha particles
(Elsevier, 1970-05-25)
Cross sections for inelastic scattering of 45 MeV [alpha] particles from 140Ce and 208Pb have been measured for angles as small as 8O. Coulomb excitation has been found to be a significant contributor to the cross sections ...
Parafluidity in helium near the λ-transition and the generalized time-dependent Landau theory
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1970-06)
A phenomenological theory of parafluidity, i.e., an enhancement of fluidity due to order-parameter fluctuations, is presented for helium near the λ transition. The generalized time-dependent Landau theory of second-order ...
Bacterial luminescence: In vivo and in vitro response to X irradiation
(Elsevier, 1970-11)
Bacterial luminescence is suppressed immediately by X rays and recovers promptly thereafter. This effect is similar in vivo and in vitro, and any disparities are attributed to physicochemical differences between the two ...
Relaxation time and effective mass of ions in liquid helium
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1970-03)
A measurement of momentum relaxation times for charged particles in liquid helium is reported. The method is to measure the change in the reflection coefficient of a microwave cavity caused by the admission of ions. The ...
Anisotropic Electron Spin Resonance Spectrum of PF2 in Low‐Temperature Matrices
(The American Institute of Physics, 1970-02-01)
The anisotropic electron spin resonance spectrum of the PF2 radical has been observed. P2F2 was thermally decomposed by passing the gas over a hot wire. The radicals produced were trapped in an argon matrix on a flat ...
