One-proton
bound state known:
|
|
|
– |
7Be(0p3/2+0p1/2)|2+
at -0.137 MeV
|
|
|
|
| • |
Need
spectroscopy of non-resonant
|
|
|
continuuum!
|
|
|
– |
B(E1) &
B(E2) for transition ps,d need to be
|
|
accurately
known
|
|
|
|
– |
E1
and E2 amplitudes interfere in p||(7Be)
|
|
|
|
|
momentum
distribution
|
|
|
|
– |
so measure
relative E2/E1 amplitudes from
|
|
|
asymmetries.
