• $$N\bar N$$ resonance and the corrections to the Goldberger-Treiman relationresonance and the corrections to the Goldberger-Treiman relation

The relevance of the recent experimental observation of possible bound and resonant states in$$N\bar N$$ scattering to the Goldberger-Treiman (GT) relation is examined. It is pointed out that anS-wave resonance in$$N\bar N$$ scattering goes a long way towards accounting for the corrections to the GT relations. Values of the mass and width of the resonance capable of giving a reasonable fit for the GT relation are presented.

• On the energy spectra of one-dimensional anharmonic oscillators

In this paper we present explicit and simple analytical formulae for the energy eigenvaluesEn (λ) of one-dimensional anharmonic oscillators characterized by the potentials 1/22x2x withα=2, 3 and 4. A simple intuitive criterion supplemented by the requirement of correct asymptotic behaviour, has been employed in arriving at the formulae. Our energy values over a wide range ofn andλ are in good agreement with the numerical values computed by earlier workers through very elaborate techniques. To our knowledge this is the first time that formulae of such wide validity have been given. The results for pure power oscillators are trivially obtained by going over to theω→0 limit. Approximate analytic expressions for the low order even moments ofx are also given.
