Equivalence Theorems for Pseudoscalar Coupling
(American Physical Society, 1952-09-15)
By a unitary transformation a rigorous equivalence theorem is established for the pseudoscalar coupling of pseudoscalar mesons (neutral and charged) to a second-quantized nucleon field. By the transformation the linear ...
Empirical Determination of Nuclear Moments of Inertia and Intrinsic Quadrupole Moments
(American Physical Society, 1956-08)
Ruby as a Maser Material
(The American Institute of Physics, 1959-07)
The reasons for the initial choice of ruby as a maser material are outlined and some measurements of the parameters in the spin Hamiltonian and of spin relaxation times are reported. The relative merits of single‐ and ...
The Second-Quantized Theory of Spin-1/2 Particles in the Nonrelativistic Limit
(American Physical Society, 1952-05-01)
The second-quantized Dirac Hamiltonian for free electrons is transformed by a canonical transformation to a representation in which the positive and negative energy wave operators are separately represented by two-component ...
