Asymptotic normalization coefficient method for two-proton radiative capture

Physics Letters B, 2020
The method of asymptotic normalization coefficients is a standard approach for studies of two-body non-resonant radiative capture processes in nuclear astrophysics.

Nuclear Structure and Simple Nuclear Reactions [PDF]

Physical Review, 1960
Recently it has become increasingly evident that some assumptions in the nuclear model used for the Monte Carlo calculations yield cross section values which are not in accord with experiment. In particular, calculations of ($p, \mathrm{pn}$)-reaction cross sections in the Bev energy range give values which are low by factors of two to nine when ...

The status of new fragment separator ACCULINNA-2 project and the first day experiments

EPJ Web of Conferences, 2014
The new facility fragment separator ACCULINNA-2 will be put into operation at the beginning of 2015 in FLNR JINR. The new separator is destined to add considerably to the studies of drip-line nuclei performed with the use of variety of direct reactions ...

Investigating the predicted breathing-mode excitation of the Hoyle state

Physics Letters B, 2022
Knowledge of the low-lying monopole strength in C12—the Hoyle state in particular—is crucial for our understanding of both the astrophysically important 3α reaction and of α-particle clustering. Multiple theoretical models have predicted a breathing mode

The role of Fission in the search of the Super Heavy Land: Fission modes in heavy and superheavy nuclei. Case study of 180Hg [PDF]

EPJ Web of Conferences
Many observations strongly support the hypothesis that nuclei may fission through several independent fission modes (multimodal fission) interpreted as different prescission shapes and fission paths in a multidimensional potential energy landscape where ...

Role of neutron rearrangement channels in sub-barrier fusion

EPJ Web of Conferences, 2015
Different factors influencing the sub-barrier fusion enhancement owing to neutron rearrangement with positive Q values are studied. It was found that opposite to the previous opinion the presence of positive Q values is necessary but not sufficient to ...
