Lack of access to quality health care for a large number of Americans, particularly those living in rural areas, is a major health care problem. Differences in access between rural and urban areas are caused by obstacles to providing adequate care, such as hospital closures and physician shortages, and low income and/or employment that does not provide health insurance as an employee benefit. This study, based on a random sample of 6,000 households in Nebraska, finds that access to health care is better for residents of rural than urban areas. The relationship holds with controls for health status and health insurance. The pattern in Nebraska reflects an absence of differences in income, health insurance, and health status that produce differences in access between rural and urban areas nationwide. The findings suggest that any serious proposal to reform health care delivery should involve the states and use established patterns of seeking care among state residents.

Doubly excited neutral states of neon, 2s22p4nln'l', have been investigated using photoelectron spectroscopy with synchrotron radiation. The selective decay of these levels into all the energetically accessible ionic states in the range 50-60 eV has been measured. In addition, decay of Ne+ states, with binding energies above the first double ionisation potential, by autoionisation to the Ne2+(3P) state has been observed. 45 46 47 48 49Photon energy lev)

Doubly excited neutral states of argon have been investigated by observing their decay into the 3p and 3s main ionisation lines and into the satellite ionic states. These were measured using photoelectron spectroscopy and monochromatic synchrotron radiation in the range 31.0 to 42.3 eV. The 3p and 3s main line constant ionic state spectra show structure due to the decay of doubly excited states but in general these are much less prominent than in the spectra for the satellites which are dominated by resonances, particularly close to threshold. There is also a strong selectivity with marked differences in the resonance structure observed in the decay to different satellite states. Four Rydberg progressions have been observed each of which is split into two series.

A study has been made of photodissociation processes in O2 which produce autoionizing fragments. Tunable VUV radiation was used to obtain photoelectron spectra. These contain structure due to electron emission from states of atomic oxygen decaying to the ground and first excitated states of the ion. The investigation has concentrated on the region of the thresholds for the production of the atomic autoionization, and spectra have also been recorded up to 60 eV photon energy.
