  If one examines two-body matrix elements from experiment one notices that not
only J=0 T=1 lies low but also J=1T=0 and J=J_{max} =2j T=0. It is sometimes
thought that one needs both T=1 and T=0 two-body matrix elements to get equally
spaced spectra of even I states i.e. vibraitonal spectra. We here attempt to
get equally spaced levels with only those that have T=1 (even J).As an example
we perform single-j calculations (f_{7/2}) in ^{44} T and ^{46} Ti. We then
shift gears and decide to play around with the input two particle matrix,
elements (not worrying about experiment) to generate interesting spectra e.g.
rotaional spectra with and then without T=0 two-body matrix element. Of special
interest is a new partial dynamical symmetry found when the "123", the "1234"
etc.,interactions are used.
