Systematic of fusion incompleteness in reactions induced by α cluster projectiles

Abstract: In order to investigate the systematic of fusion incompleteness in reactions induced by $\ensuremath{\alpha}$ cluster projectiles, a detailed study was carried out using the $^{20}\mathrm{Ne}+^{165}\mathrm{Ho}$ system at energies above the barrier. Measurements of the excitation function (EF) of the observed evaporation residues (ERs) were carried out by employing the offline characteristic $\ensuremath{\gamma}$-ray detection method. The EFs of the ERs populated through $xn/pxn$ channels were found to be in good agreement with the prediction of the statistical model code pace4, whereas the EF of the ERs populated through the $\ensuremath{\alpha}$ emitting channels shows an enhancement over the pace4 prediction. The degree of fusion incompleteness in the $^{20}\mathrm{Ne}+^{165}\mathrm{Ho}$ reaction is estimated by comparing the fusion EF with coupled channels calculations and the extracted fusion function with the universal fusion function. The influence of input angular momentum on fusion reaction dynamics is explored in light of the sum-rule model. An attempt has also been made to examine the dependence of incomplete fusion probability on various entrance channel parameters.

Monitoring of Metal Deposition by Moss Barbula Constricta J. Linn., from Mussoorie Hills in the India

Abstract: The moss Barbula constricta J. Linn. was used as an active bio-monitor for estimation of atmospheric metal deposition and its seasonal trend to assess the metal (Zn, Pb, Cu, Cd) status of Mussoorie city and its adjoining areas. Moss transplants were exposed for four months, each period representing winter, summer and monsoon season data at the distances of 0.5, 1.0 and 3.0 km during 2003 to 2007. Significantly higher levels of Zn, Pb, and Cu were measured in the moss harvested at the end of each season. The values of metals at different distances from the city center were higher than in the background samples treated as control. Patterns of moss analysis for seasonal and annual metal data were closely identical. Values of metals were the highest during summer followed by winter, and the lowest in monsoon. It was found that an increase recorded in the sampling sites in the past 5 years could be due to the rapid economic development and the manifold increase in tourist activities. Results from the present moss surveys make the examination of both spatial and temporal trends of metals possible, and also confirm the validity of moss B. constricta J. Linn. as a reliable bio-monitor, and recommend it for the bio-mapping program. Data from existing surveys of metal concentrations in moss is filling a gap due to very limited information available in this field. In addition, it is an invaluable resource for policy makers in preparing the strategies for mitigation. DOI: http://dx.doi.org/10.5755/j01.erem.67.1.1750

Effect of Silica Gel ‘G’ on the Ion Exchange Behaviour of Antimonic Acid Thin Layers in The Chromatographic Study of Anions in Some Aqueous Organic Acid Systems: Determination of Ferricyanide and Dichromate Ions

Abstract: The ion exchange potential of antimonic acid and silica gel ‘G’ has been explored in thin layer chromatographic studies for the separation of anions. Several important and difficult binary separations of anions have been achieved as a result of these studies. Io− 3-Bro− 3, I−-Io− 3, Io− 4-Io− 3, Io− 4-Po−- 4, Br−-Bro− 3, Aso−- 4-Cro−- 4, S2o−- 3-Po−- 4, CNS−-S2o−- 3, Io− 4-Cro−- 4, Bro− 3-Cro−- 4, Io− 3-Cr2o−- 7 and s2o3-Cro−- 4 etc. are separations of analytical interest. Besides, a rapid microgram determination of [Fe(CN)6]3− (1–10 μg) and Cr2o2- 7 (2–10 μg) ions have been made.
