Nuclear fusion and generalized Gamow penetrability factor in intense laser fields

A theoretical study on nuclear fusion including deuteron-triton (D-T) and deuteron-helium-3 fusion (D-He-3) fusion in intense laser fields has been presented in this article. With the laser fields expected to be available soon, some quantitative results for the laser-induced modifications to the cross-sections are given. It is reported that the cross-section of the fusion reaction is more sensitive to the external laser fields when the incident nucleus has lower energy. An explicit generalized form of the Gamow penetrability factor is given for the predictions of the laser-induced effects for some other similar nuclear processes. (c) 2022 Elsevier B.V.

This article presents a theoretical study on nuclear fusion of deuteron-triton (D-T) and deuteron-helium-3 (D-He-3) in intense laser fields. Quantitative results for the laser-induced modifications to the cross-sections are provided, indicating that the fusion reaction cross-section is more sensitive to the external laser fields at lower incident nucleus energy. An explicit generalized form of the Gamow penetrability factor is also given for predicting laser-induced effects in similar nuclear processes.
