The nondissociative electron impact ionization cross section of the metastable N2(A 3Σ+u) state is measured from threshold to 240 eV. Rising from an appearance potential of 10.1±0.6 eV, the cross section peaks at about 40 eV with a value of (1.14±

The relaxation behavior of the He–HD system is studied by applying an exponential distorted wave procedure to calculate the cross sections and the rate constants for vibrational–rotational energy transfer in the vibrational manifolds n, 0⩽n⩽5

High‐Rydberg (HR) molecules of H2, D2, N2, and CO have been observed with lifetimes of the order of 100 μsec. They are stable with respect to predissociation and autoionization and have sufficiently long radiative lifetimes to be detected because

In this work we report the observation of polyatomic high‐Rydberg molecules which survive for several hundred microseconds. Methane and ethane were excited by electron impact to produce high‐Rydberg states of their fragments: CH3 from methane and

An inexpensive and accurate technique for computing inelastic cross sections has been developed by combining an exponential distorted wave (EDW) approximation and an effective Hamiltonian. This procedure is implemented through the use of uniformized

High-Rydberg atoms are produced by an electron beam passing through each of the rare gases at \ensuremath{\sim}${10}^{\ensuremath{-}6}$ Torr and are detected by electric field ionization after traveling 20.1 cm at thermal velocity. Their principal qu

Threshold-energy peaks are observed for electron impact excitation of N/sub 2/ and H/sub 2/ to high-Rydberg states. These peaks are attributed to the direct excitation of high-lambda states near threshold consistent with the prediction of Fano.
