Abstract:

Experimental and theoretical atomic physics at New York University is described. The experimental work includes 1 total low energy e-O and e-O2 cross sections 2 Tensor Polarizabilities of metastable Hg 3 threshold behavior of 4 doublet-P12,32 states of K by electron bombardment and state selection of K beam 4 Cold 150K microwave discharge atomic beam H source 5 new e-molecule total cross-section and tensor polarizability apparatus 6 new e-metastable rare gases total cross sections experiment 7 Li beam Cs plasma interactions. The theoretical scattering work includes 1 long range potentials and functions required in partial-wave effective range theory 2 Variational lower and upper bounds on phase shifts 3 variational bounds on parameters using Feynman formulation of Q.M. 4 comparison of variational bound formalisms 5 conditions for existence of bound states 6 bounds on matrix elements 7 collective oscillations of atoms.
