Abstract

Time-of-flight scattering measurements at 8.65 eV (c.m.) display strong inelastic scattering from

He (2 {}^{3}S) + He (1 {}^{1}S)

He (2 {}^{3}P) + He (1 {}^{1}S)

. Close-coupled quantum-mechanical calculations employing ab initio potential curves and matrix elements show the inelastic process is due to strong rotational coupling between the

c {}^{3}Σ_{g}^{+}

state of

He (2 {}^{3}S) + He (1 {}^{1}S)

and the

b {}^{3}Π_{g}

state of

He (2 {}^{3}P) + He (1 {}^{1}S)

. Good agreement is found between the calculated and the experimentally measured inelastic-scattering cross sections.
