    Notes: Abstract: The inclusive energy spectra of light charged particles, such as, α, p, d and t, evaporated from the hot 31P nucleus at an excitation energy E *∼ 60 MeV, have been measured at various angles. The compound nucleus 31P has been populated using two different entrance channel configurations; i.e., 7Li (47 MeV) + 24Mg and 19F (96 MeV) + 12C reactions, leading to the same excitation energy of the compound system. It has been observed that the spectra obtained in the 7Li (47 MeV) + 24Mg reaction follow the standard statistical-model prediction with a spherical configuration of the compound nucleus. But, the spectra obtained in the 19F (96 MeV) + 12C reaction deviate from similar predictions of the statistical model both on higher- as well as on lower-energy sides. Considerable deformation was required to be incorporated in the calculation in order to reproduce the measured-energy spectra in this case. Dynamical trajectory model calculations were not found to play any significant role in explaining the differences in behaviour between the two cases under study. The observed discrepancy has been attributed to the difference in the angular-momentum distributions of the compound nuclei formed in the two reactions.

    Phenomenological analysis of intermediate mass fragments emission in alpha induced reactions (1993)

    Notes: Abstract Intermediate mass fragment emission in α induced reactions on Al and Ti at 60 and 104 MeV, respectively has been analysed using phenomenological moving source model. Fragment emission at backward angles is found to be well explained by a single fusion-like source, whereas for forward angles an additional intermediate velocity source is required to explain the data. The relative contribution of the intermediate velocity source decreases sharply with angle for lower energies and it extends significantly to larger angles in the higher energy reaction. The fractional momentum transfer for the fusion-like source is in agreement with the corresponding Viola systematics value in the case of α+Al reaction, whereas for α+Ti reaction, it is larger than that obtained from the Viola systematics. The degree of incompleteness (in momentum transfer) is found to be fragment dependent; incompleteness being more for lighter fragments and vice-versa.

    The relationship between the marketing mix and share of category requirements (1996)

    Notes: Abstract A criticism of purchase-based brand loyalty measures is that they are confounded by the marketing mix variables that affect brand choice. This paper investigates the magnitude and direction of the associations for share of category requirements (SCR), defined as each brand's share among the group of households who bought the brand at least once during the time period under consideration. We discuss the theoretical foundations for the relationships between SCR and a set of marketing mix variables (price, promotions, retail distribution) and conduct a latent structure regression analysis of brand-level data to test these relationships. We find that, although the relationship between the marketing mix variables and SCR is statistically significant, in real terms the magnitude of the association is fairly low.

    Mass and charge distribution in232Th(α, f) reaction in the projectile energy range 28 to 72 MeV (1993)

    Notes: Abstract The cumulative yields for 13 short-lived neutron rich nuclei in the mass rangeA=99 toA=118, produced via the232Th (α, f) reaction were determined at four incident beam energies covering the range from 28 to 72 MeV usingγ-spectroscopy of fission products. The charge distribution parameter Z p was determined for theA=99 mass chain at all the four incident beam energies of 28.5, 39.7, 50.8 and 71.4 MeV and was found to fit into a description of fission process with unchanged charge division (UCD). The measured cumulative yields were converted into chain yields assuming UCD and the yieldmass distribution was obtained at all the above energies. The mass distribution remains asymmetric even at 71.4 MeV, the highest energy studied in this work. The excitation energy dependence of the mass and the charge distribution and of the cumulative yields indirectly suggests that the fission has predominantly proceeded from a relatively low level of excitation allowing most of the excitation energy to be carried away by light particles prior to scission.
