Method for Measuring the Laser Field and the Opacity of Spectral Lines in Plasmas
Plasma, 2021 In experimental studies of laser-plasma interactions, the laser radiation can exist inside plasma regions where the electron density is below the critical density (“underdense” plasma), as well as at the surface of the critical density.

Spectroscopic amplitudes for α-clustering in 6Li and 7Be
Physics Letters B, 1984 Abstract Spectroscopic amplitudes for α -clustering in the bound states of 6 Li and 7 Be are computed by adopting the definition of Fliessbach. The wavefunctions used are those from coupled-channel resonating-group calculations. Using these amplitudes, one can determine the spectroscopic factor and the constant characterizing the asymptotic ...

Probing the 6Li cluster structure with alpha-particle elastic scattering
Eurasian Journal of Physics and Functional Materials, 2022 The three-body model α + n + p for 6Li is applied as a probe with elastic scattering of α -particles. Elastic scattering is described within the optical model framework, while the rising of the cross section at the backward scattering angles is treated ...

Radial velocity variations of the pulsating subdwarf B star PG 1605+072 [PDF]
, 2001 We present an analysis of high-speed spectroscopy of the pulsating subdwarf B star PG 1605+072. Periodic radial motions are detected at frequencies similar to those reported for photometric variations in the star, with amplitudes of up to 6 km/s ...

Calculation of spectroscopic amplitudes using boson expansion wave functions [PDF]
Nuclear Physics A, 1975 Abstract A formalism is derived which allows the evaluation of spectroscopic amplitudes for two-nucleon transfer reactions. The transfer is assumed to take place between low-lying collective states described by boson expansion wave functions. Numerical calculations have been performed for (t, p) reactions on148, 150, 152Sm.

Elastic and inelastic scattering of 18O ions on 12C nuclei [PDF]
Ядерна фізика та енергетика, 2009 Angular distributions of the 12C + 18O elastic and inelastic scattering were measured at the energy Elab(18O) = 105 MeV (Ec.m. = 42 MeV). These data and data known from the literature at the energies Ec.m. = 12.9 - 56 МеV were analysed within the optical

Astrophysical $S$ factor for the ${}^{15}{\rm N}(p,\gamma){}^{16}{\rm O}$ reaction from $R$-matrix analysis and asymptotic normalization coefficient for ${}^{16}{\rm O} \to {}^{15}{\rm N} + p$. Is any fit acceptable? [PDF]
, 2011 The $^{15}{\rm N}(p,\gamma)^{16}{\rm O}$ reaction provides a path from the CN cycle to the CNO bi-cycle and CNO tri-cycle. The measured astrophysical factor for this reaction is dominated by resonant capture through two strong $J^{\pi}=1^{-}$ resonances ...

Unitary correlation in nuclear reaction theory
, 2010 We prove that the amplitudes for the (d,p), (d,pn) and (e,e'p) reactions determining the asymptotic behavior of the exact scattering wave functions in the corresponding channels are invariant under unitary correlation operators while the spectroscopic ...
