Comment on "Hadronic He production near threshold"
K. P. Khemchandani, N. G. Kelkar, B. K. Jain
Measurements of the differential and total cross sections for the He reaction at five energies were recently reported [Phys. Rev. C {\bf 75}, 014004 (2007)] and com…
Critical view of WKB decay widths
N. G. Kelkar, H. M. Castaneda
A detailed comparison of the expressions for the decay widths obtained within the semiclassical WKB approximation using different approaches to the tunneling problem is performed.…
Quantum reflection and dwell times of metastable states
Neelima G. Kelkar
The concept of phase and dwell times used in tunneling is extended to quantum collisions to derive a relation between the phase and dwell time delays in scattering. This relation c…
A study of the reaction
N. J. Upadhyay, K. P. Khemchandani, B. K. Jain +1
A study of the reaction in the energy range where the recent data from Uppsala are available, is done in the two-step model of production including the final st…
