Medium energy nuclear physics research
The UMass group has concentrated on using electromagnetic probes, particularly the electron in high-energy scattering experiments at the Stanford Liner Accelerator Center (SLAC). Plans are also being made for high energy work at the Continuous Beam Accelerator Facility (CEBAF). The properties of this accelerator should permit a whole new class of coincidence experiments to be carried out. At SLAC UMass has made major contributions toward the plans for a cluster-jet gas target and detector system at the 16 GeV PEP storage ring. For the future CEBAF accelerator, tests were made of the feasibility of operating wire drift chambers in the vicinity of a continuous electron beam at the University Illinois microtron. At the same time a program of studies of the nuclear structure of more complex nuclei has been continued at the MIT-Bates Linear Accelerator Center and in Amsterdam at the NIKHEF-K laboratory. At the MIT-Bates Accelerator, because of an unforeseen change in beam scheduling as a result of problems with the T{sub 20} experiment, the UMass group was able to complete data acquisition on experiments involving 180{degrees} elastic magnetic scattering on {sup 117}Sn and {sup 41}Ca. A considerable effort has been given to preparations for a future experiment at Bates involving the high-resolution threshold electrodisintegration of the deuteron. The use of these chambers should permit a high degree of discrimination against background events in the measurement of the almost neutrino-like small cross sections that are expected. In Amsterdam at the NIKHEF-K facility, single arm (e,e{prime}) measurements were made in November of 1987 on {sup 10}B in order to better determine the p{sub 3/2} wave function from the transition from the J{sup pi} = 3{sup +} ground state to the O{sup +} excited state at 1.74 MeV. In 1988, (e,e{prime}p) coincidence measurements on {sup 10}B were completed. The objective was to obtain information on the p{sub 3/2} wave function by another means.
