Electric fields at finite temperature
A. Bermudez Manjarres, N. G. Kelkar, Marek Nowakowski
Partial differential equations for the electric potential at finite temperature, taking into account the thermal Euler-Heisenberg contribution to the electromagnetic Lagrangian are…
Tunneling times and bremsstrahlung in alpha decay
N. G. Kelkar, M. Nowakowski
A semi-classical model based on quantum time concepts is presented for the evaluation of bremsstrahlung emission probabilities in alpha decay of nuclei. The contribution to the bre…
Quantum time scales in alpha tunneling
N. G. Kelkar, H. M. Castaneda, M. Nowakowski
The theoretical treatment of alpha decay by Gamow is revisited by investigating the quantum time scales in tunneling. The time spent by an alpha particle in front of the barrier an…
Analysis of averaged multichannel delay times
N. G. Kelkar, M. Nowakowski
The physical significances and the pros and cons involved in the usage of different time delay formalisms are discussed. The delay time matrix introduced by Eisenbud, where only s-…
Breit type equation for mesonic atoms
N. G. Kelkar, M. Nowakowski
The finite size effects and relativistic corrections in pionic and kaonic hydrogen are evaluated by generalizing the Breit equation for a spin-0 - spin-1/2 amplitude with the inclu…
Neutron structure effects in the deuteron and one neutron halos
M. Nowakowski, N. G. Kelkar, T. Mart
Although the neutron (n) does not carry a total electric charge, its charge and magnetization distributions represented in momentum space by the electromagnetic form factors, $F_1^…
Hidden evidence of non-exponential nuclear decay
N. G. Kelkar, M. Nowakowski, K. P. Khemchandani
The framework to describe natural phenomena at their basics being quantum mechanics, there exist a large number of common global phenomena occurring in different branches of natura…
Evidence of Pentaquark States from K+ N Scattering Data?
N. G. Kelkar, M. Nowakowski, K. P. Khemchandani
Motivated by the recent experimental evidence of the exotic B = S = +1 baryonic state Theta(1540), we examine the older existing data on K+ N elastic scattering through the time de…
