Cross talk between experimental data and simple validation of shell closure in pre-actinides
Punit Dubey, Mahima Upadhyay, Mahesh Choudhary +13
Two back-to-back experiments, 28Si + 178Hf and 28Si + 186W, were intentionally conducted to validate the role of shell closure in pre-actinides by studying neutron multiplicity in…
To examine the variation in dissipation near the shell closure using neutron multiplicity as a probe
Punit Dubey, Mahima Upadhyay, Mahesh Choudhary +12
The pre and post-scission neutron multiplicities have been determined for the fission of the compound nucleus (CN) 206Rn, induced by the reaction 28Si+178Hf within the excitation e…
Moments of inertia of rare-earth nuclei and the nuclear time-odd mean fields within exact solutions of the adiabatic theory
Xuwei Sun, Jacek Dobaczewski, Markus Kortelainen +3
We systematically analyse the nuclear moments of inertia determined within the Skyrme and Gogny density functional theories. The time-odd mean fields generated by collective rotati…
Iterative solutions of the ATDHFB equations to determine the nuclear collective inertia
Xuwei Sun, Jacek Dobaczewski, Markus Kortelainen +4
An iterative adiabatic time-dependent Hartree-Fock-Bogoliubov (ATDHFB) method is developed within the framework of Skyrme density functional theory. The ATDHFB equation is solved i…
Multimodal fission from self-consistent calculations
Daniel Lay, Eric Flynn, Sylvester Agbemava +4
When multiple fission modes coexist in a given nucleus, distinct fragment yield distributions appear. Multimodal fission has been observed in a number of fissioning nuclei spanning…
Nudged elastic band approach to nuclear fission pathways
Eric Flynn, Daniel Lay, Sylvester Agbemava +4
The nuclear fission process is a dramatic example of the large-amplitude collective motion in which the nucleus undergoes a series of shape changes before splitting into distinct f…
Theoretical description of fission yields: towards a fast and efficient global model
Jhilam Sadhukhan, Samuel A. Giuliani, Witold Nazarewicz
Background: A quantitative microscopic understanding of the fission-fragment yield distributions represents a major challenge for nuclear theory as it involves the intricate compet…
Evidence for the reduction of nuclear level density away from the -stability line
Pratap Roy, K. Banerjee, T. K. Rana +14
The isospin dependence of nuclear level density has been investigated by analyzing the spectra of evaporated neutrons from excited Sn and Te nuclei. These nuclei ar…
Future of Nuclear Fission Theory
Michael Bender, Remi Bernard, George Bertsch +30
There has been much recent interest in nuclear fission, due in part to a new appreciation of its relevance to astrophysics, stability of superheavy elements, and fundamental theory…
Efficient method for estimation of fission fragment yields of r-process nuclei
Jhilam Sadhukhan, Samuel A. Giuliani, Zachary Matheson +1
More than half of all the elements heavier than iron are made by the rapid neutron capture process (or r process). For very neutron-rich astrophysical conditi…
Cluster radioactivity of Og
Zachary Matheson, Samuel A. Giuliani, Witold Nazarewicz +2
According to theory, cluster radioactivity becomes an important decay mode in superheavy nuclei. In this work, we predict that the strongly-asymmetric fission, or cluster emission,…
A dynamical model calculation to reconcile the nuclear fission lifetime from different measurement techniques
M. T. Senthil Kannan, Jhilam Sadhukhan, B. K. Agrawal +2
The pre-scission particle multiplicities suggest a lifetime of 10 20 s for the nuclear fission to occur which is in contrast to the fission lifetime 10 18 s as predicted by atomic…
First observation of the competing fission modes in the neutron-deficient sub-lead region
I. Tsekhanovich, A. N. Andreyev, K. Nishio +12
Fragment mass distributions from fission of excited compound nucleus Pt have been deduced from the measured fragment velocities. The Pt nucleus was created at the J…

Direct Evidence of Washing out of Nuclear Shell Effects
A. Chaudhuri, T. K. Ghosh, K. Banerjee +12
Constraining excitation energy at which nuclear shell effect washes out has important implications on the production of super heavy elements and many other fields of nuclear physic…
Pairing-induced speedup of nuclear spontaneous fission
Jhilam Sadhukhan, J. Dobaczewski, W. Nazarewicz +2
Collective inertia is strongly influenced at the level crossing at which quantum system changes diabatically its microscopic configuration. Pairing correlations tend to make the la…
