We also take into account the effect of isospin
mixing between I = 0 and I = 1, as well as possible [SIGMA] (1385) contamination in the observed spectrum.
In the concept of isospin
, proton and neutron are viewed as two states of the same quantum oscillator.
By considering the isospin
symmetric modes of the measured channels, we can estimate the lower limits on the leptonic partial width of the Y(4220) and Y(4390) decays.

effects in heavy-ion collisions at intermediate energies," Physical Review C, vol.
Among the topics are no-core shell model and reactions, direct reactions with exotic nuclei, isoscaling and symmetry energy in dynamical fragment formation, "pasta" phases in dense stars, and isospin
effects on fragmentation mechanisms.
In the case of the strong interaction, the gauge symmetry is the isospin
symmetry--the strong interactions are invariant under rotations in the isospin
[G.sub.V] may be determined from the measured ft-values of the pure Fermi [0.sup.+] - [0.sub.+] superallowed [beta]-transitions within isospin
triplets provided the relevant nuclear physics corrections may be applied with confidence .
Por ejemplo, en la interaccion fuerte entre neutrones y protones se conservan, aparte de la paridad, magnitudes tales como la masa llamada barionica (numero total de protones y neutrones), el isospin
y la hipercarga, que no se conservan en la interaccion electrodebil.
Johnson orders his story around the progression of theories and discoveries in quantum thinking, providing an extraordinary wealth of detail on such recondite topics as particle parity, mathematical renormalization, isospin
, and quantum chromodynamics.
