The process μ−+12C→12B+
As far as the partial capture rate is concerned the use of the unitary-model operator approach wave functions for12C with
The12B(1+; g.s) recoil polarisation is found to be insensitive to the use of the unitary-model-operator-approach wave functions. When compared with the experimental data, we obtain
The total capture rate is found to be sensitive to the use of the unitary-modeloperator-approach wave functions which contain the effect of nucleon-nucleon short range correlations and we obtain a satisfactory agreement with the experiment for16O and12C, thereby revealing the importance of the effect of such correlations in the total capture rate studies.

It is shown that the fermion number in a five-dimensional Kaluza-Klein theory (M4×S1) in which the fermion is interacting with a monopole field, is quantized in units of (ϕR)2 where the scalar ϕ is asymptotically constant and

Gribov ambiguity in gauge field theories is discussed and it is shown that such an ambiguity exists even for Abelian theories in covariant gauge at finite temperature. Both geometric and algebraic proofs are presented. In view of the importance of non-perturbative methods, some special gauges are given in which such ambiguities do not exist or are not relevant. The significance of these in the study of confinement in QCD is pointed out.
