Neutron radii and semi-phenomenological treatment of neutron distributions for Mg isotopes

Govind Kumar, M. Imran, Z. Hasan +1

Involving the charge radii of \rm Mg isotopes, as calculated using the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc), we have extracted the neutron radii of…

On energy-dependent scaling factor for the charge-changing cross sections of light elements

Z. Hasan, M. Imran, A. A. Usmani +1

In this study, the scaling factor for \rm Si + \rm C charge-changing cross sections (CCCSs) at 90-1296 MeV/nucleon has been used as a basis to introduce the energy de…

Theoretical investigation of charge-changing cross section and interaction cross section for Be, B, C, N, O, and F isotopes on C at 200-1050 MeV/nucleon

Z. Hasan, M. Imran, A. A. Usmani +1

To establish credibility for the use of the Slater determinant harmonic oscillator (SDHO) density in predicting root-mean-square proton and neutron radii for Be, B, C, N, O, and F…

Charged gravastars admitting conformal motion

A A Usmani, Farook Rahaman, Saibal Ray +4

We propose a new model of a {\it gravastar} admitting conformal motion. While retaining the framework of the Mazur-Mottola model, the gravastar is assumed to be internally charged,…

Thin-shell wormholes from charged black holes in generalized dilaton-axion gravity

A. A. Usmani, F. Rahaman, Saibal Ray +3

This paper discusses a new type of thin-shell wormhole constructed by applying the cut-and-paste technique to two copies of a charged black hole in generalized dilaton-axion gravit…

Behaviour of the potentials due to strangeness degree of freedom in He hypernucleus

A. A. Usmani, Z. Hasan

Fully correlated study of He hypernucleus has been performed with two- and three- baryon potentials. For the S=-2 sector, various simulations of Nijmegen potential m…
