    Afzal, F A (J. Phys. E: Sci. Instrum., 1974-01-01)
    A graphite tube electric furnace has been designed to facilitate measurement of electrical properties of small refractory samples at high temperatures. Conductivity data are obtained with the sample at a uniform temperature ...
  • Study of the reaction K-p→ηΛ 
    Fazal -e-Aleem; Saleem, Mohammad; Qureshi, Imtinan Elahi (Communications in Theoretical Physics, 1983-01-01)
    It is shown that at high energy all available data for differential and integrated cross sections and Λ-polarisation in the reaction K-p→ηΛ can be fitted by using a simple Regge pole model with phenomenological residue ...
  • Pulsar supernova remnant correlation 
    Qadir, A; Rafique, M (1986-01-01)
    A formula is provided to check the correlation of pulsars and supernova remnants, using only observable pulsar parameters. The validity of this formula depends on the assumption that the value of the initial pulsar frequency ...
  • Pseudo-Newtonian Potentials 
    Qadir, A.; Quamar, J. (Institute of Physics, 1986-01-01)
    The conjecture that the relativistic analogue of the Newtonian gravitational potential is given by the square of the magnitude of the Killing vector is proved for a class of space-times. An interesting consequence of this ...
  • Pulsar drift and rotational collapse 
    Asghar, Qadir; Rafique, M; Siddiqui, A W (Institute of Physics (IOP), 1987-01-01)
    The relativistic explanation of pulsar drift is based on an extremely simplistic model. The collapsing star is treated as composed of a collection of particles falling radially inwards. A calculation incorporating a finite ...
  • Decay of a whistler wave in a hot-ion plasma 
    Saleem, H (Institute of Physics, 1987-01-01)
    The decay of a whistler wave into an electron acoustic wave and a lower hybrid wave in a hot-ion plasma is considered. The growth rate of the decay instability is calculated and shown to be comparable to those of other ...

    Rizvi, S A H (Physica Scripta, 1987-01-01)
    The constructive interference between the two oppositely propagating lasers can produce a forced stationary electron density ripple. The latter can reflect the incident laser light from an expanding plasma in the underdense ...
  • Laser Light Reflection from an Expanding Plasma 
    Rizvi, S A H (Physica Scripta L, 1987-01-01)
