    Antibunching effects in resonant raman scattering involving laser fields of arbitrary strengths (1979)
    Springer
    The European physical journal 35 (1979), S. 391-397

    ISSN: 1434-6036

    Notes: Abstract Using the recently developed theory of resonant Raman scattering in the presence of strong double frequency fields, the statistical properties of the spontaneously emitted Stokes and Rayleigh radiation are calculated. In particular, the temporal intensity correlations of arbitrary order are evaluated. It is found that they possess the property of factorization in terms of the probabilities for finding the system in the resonant intermediate excited state when the starting state is the given initial state and when the starting state is a particular superposition of the ground and final excited states. The weight-factors in the particular superposition depend on the direction of observation and on the transition dipole-moments. The second-order intensity correlation is shown to have the complete anti-bunching property. The factorization property of the intensity correlations is useful in the calculation of photo-electron counting distributions.

    Variability in nuclear DNA content within pigeonpea,Cajanus cajan (Fabaceae) (1994)
    Springer
    Plant systematics and evolution 189 (1994), S. 211-216 
    Details
    ISSN: 1615-6110
    Keywords: Fabaceae ; Cajanus cajan ; Nuclear DNA amount variation

    Notes: Abstract 4C DNA values have been estimated in 16 cultivars ofCajanus cajan by cytophotometry. The values range between 6.19 pg to 7.97 pg, a 23.6% variation. The cultivars form four groups which differ significantly from each other but have insignificant difference within them. The implications of this variability with respect to the heterogeneity and origin of this legume crop are discussed.

    Notes: Abstract Total seed storage protein of 9 accessions of cultivated C. cajan and 10 wild Cajanus species was reported and compared by sodium dodecyl sulphate polyacrylamide gel electrophoresis. A considerable variation was detected among the protein profiles of different accessions of C. cajan while those of wild species were very specific and distinctly different from each other. Relative similarities between various taxa were estimated by Jaccard's similarity index and cluster analysis was performed to produce a UPGMA dendrogram. The clustering of 10 wild species and C. cajan more or less agrees with their sectional classification and available data based on morphological characteristics, crossability, genome pairing in hybrids and nuclear RFLPs. The species closest to C. cajan is C. cajanifolia although the accessions of C. cajan also share some bands present in the profiles of C. scarabaeoides, C. goensis, C. lineatus, C. acutifolius and C. volubilis. This points towards polyphyletic origin of the cultigen which has been discussed in this paper.
