- Abstract
- The low-energy experimental spectra of the N=59 isotones are known to
differ greatly. Of particular note is the abrupt change in the structure
between /sup 103/Ru and /sup 105/Pd (Z=44 and 46) and between /sup 99/Zr and
/sup 101/Mo (Z=40 and 42). The authors give a cursory summary of their
investigations that have shown that they can, not only account for the
structure of /sup 105/Pd within fermion-boson model calculations, but when
they use these types of calculations for /sup 103/Ru, the fermion-boson
model exchange coupling strength (ECS) must be increased. They associate
this increase with the greater availability of the 1g/sub 9/2/ protons and
their strong interaction with the 1g/sub 7/2/ neutrons. Also, they can
account for the change between /sup 101/Mo and /sup 99/Zr within the context
of the recently discovered full set of collective excitations built on the
/sup 98/Zr intruder state and the occurrence of double subshell closure
characteristics for both /sup 96/Zr and /sup 98/Zr. (10 References).
