California Institute of Technology "For his pivotal
contributions to our understanding of the weak interaction and
fundamental symmetries in the nucleus. We especially note (1)
his measurements of positron polarization in beta decay and
their impact on the development of the V-A theory of weak
interactions, (2) his pioneering studies providing convincing
evidence for parity violation in nuclear transitions, and (3)
his frontier defining searches for violations of time-reversal
invariance in nuclei and for neutrino oscillations."Background:
Boehm pioneered the use of nuclear physics techniques to explore
fundamental questions concerning the weak interactions and the
nature of neutrinos. He developed the beta-gamma curricular
polarization correlation method as a means of establishing the
spin and angular momentum relationships in beta decay, and the
experience permitted him to make the first observation of
hadonic parity violation in a nuclear system. In addition to
searching for violations of time-reversal inv
