Abstract
Abstract A three-body classical trajectory Monte Carlo method is used to calculate the nl state-selective charge exchange cross sections in $$\hbox {Be}^{\mathrm {4+}}+$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:msup> <mml:mtext>Be</mml:mtext> <mml:mrow> <mml:mn>4</mml:mn> <mml:mo>+</mml:mo> </mml:mrow> </mml:msup> <mml:mo>+</mml:mo> </mml:mrow> </mml:math> H(2 lm ) collisions in the energy range between 10 and 200 keV/amu. We present partial cross sections for charge exchange into $$\hbox {Be}^{\mathrm {3+}}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msup> <mml:mtext>Be</mml:mtext> <mml:mrow> <mml:mn>3</mml:mn> <mml:mo>+</mml:mo> </mml:mrow> </mml:msup> </mml:math> ( nl ) $$(\textit{nl} = 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f)$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:mo>(</mml:mo> <mml:mi>nl</mml:mi> <mml:mo>=</mml:mo> <mml:mn>2</mml:mn> <mml:mi>s</mml:mi> <mml:mo>,</mml:mo> <mml:mn>2</mml:mn> <mml:mi>p</mml:mi> <mml:mo>,</mml:mo> <mml:mn>3</mml:mn> <mml:mi>s</mml:mi> <mml:mo>,</mml:mo> <mml:mn>3</mml:mn> <mml:mi>p</mml:mi> <mml:mo>,</mml:mo> <mml:mn>3</mml:mn> <mml:mi>d</mml:mi> <mml:mo>,</mml:mo> <mml:mn>4</mml:mn> <mml:mi>s</mml:mi> <mml:mo>,</mml:mo> <mml:mn>4</mml:mn> <mml:mi>p</mml:mi> <mml:mo>,</mml:mo> <mml:mn>4</mml:mn> <mml:mi>d</mml:mi> <mml:mo>,</mml:mo> <mml:mn>4</mml:mn> <mml:mi>f</mml:mi> <mml:mo>)</mml:mo> </mml:mrow> </mml:math> states as a function of impact energy. Our results are compared with the previous classical and quantum-mechanical results. We show that the classical treatment can able to describe reasonably well the charge exchange cross sections.
