  • NUCLEAR CHARGE RADIUS VARIATION IN THE NUCLEAR SHAPE TRANSITION REGION AROUND N=60-90. 
    K. K. Sirma, M. Murila; K. M. Khanna (International Journal of Advanced Research, 2020-07-01)
    The magnitude and spatial variation of the Coulomb potential within the boundaries of the atomic nucleus exhibits how a macroscopic variable, such as charge radius of the nucleus, will depend on the Coulomb potential ...
  • INTERACTION BETWEEN NEUTRON-PROTON CORE AND NEUTRON SKIN REGION IN SUPER HEAVY NUCLEI 
    K. K. Sirma; K. M. Khanna (World Scientific News, 2020-03-15)
    The core of an atomic nucleus composed of A nucleons is assumed to be composed of equal number of neutrons (N) and protons (Z); and for N>Z, the extra unpaired neutrons (N-Z) are assumed to constitute what is called ...
  • CRYSTALLIZATION OF NEUTRON MATTER (NEUTRON STARS) 
    Murunga, G. S., *Tanui, P.K.,Tonui, J. K.,Khanna, K. M., Chelimo L.S., Chelagat, I., Sirma K. K. and Cheruiyot W. K. (International Journal of Latest Engineering Research and Applications (IJLERA), 2017-06-06)
    A neutron star is the collapsed core of a large (10 – 29 solar masses) stars. Neutron stars can be considered as reservoirs of high-density fermions, as these systems can be assumed to be the largest of its type in the ...
  • CALCULATION OF CHARGE RADIUS OF NUCLEI USING THE MODIFIED COULOMB ENERGY FORMULA FOR NUCLEI 
    K. K., Sirma; K. M., Khanna (International Journal of Recent Research Aspects I, 2020-06-01)
