Induced scattering and two-photon absorption of Alfvén waves with arbitrary propagation angles

“…The main result of this paper is the expression for nonlinear damping rate (22). Results obtained differ from results [6,7] where oblique Alfvén waves were also considered. We take into account components of random field, corresponding to magnetosonic waves.…”

“…For the opposite relation one-dimensional results [2][3][4][5] and results [6,7] are valid. The results of this papers can be readily obtained if one let B zk = 0 in Eq.…”

“…It is well known now that the main nonlinear processes for such waves are induced scattering and two quantum absorption by thermal ions. Corresponding damping rates were calculated by many authors [1][2][3][4][5][6][7]. Nevertheless totally comprehensive study is absent now.…”

“…In papers [2][3][4][5] the case of wave propagation along mean magnetic field was considered. At last in papers [6,7] the oblique propagation of Alfvén waves was considered but random magnetic field component along mean magnetic field arising from magnetic pressure of Alfvén waves was not taking into account. As will be shown in this paper the last effect strongly changes resultant damping rates.…”
