197 At 195 Bi Influence of onset of deformation is seen in proton binding energies of low lying states in odd-mass At and Bi isotopes
For understanding the character of the low-lying states in the dripline Bi and At nuclei, more spectroscopic information is needed Physics case : 185 Bi 102 - proton emitter
Decay properties of 185 Bi can be studied at the focal plane of a recoil separator. Its excited states can be probed by employing in-beam RDT techniques. Possible reactions 93 Nb( 95 Mo,3n) 185 Bi, 95 Mo( 92 Mo,pn) 185 Bi, 50 nb But.....
Developments are needed 10 – 1000nA Mo beams needed Ion source developments Symmetric reactions Scattered beam at the focal plane of the separator Better recoil separators + high-granularity detector system at the focal plane High gamma-ray counting rates in in-beam measurements Digital electronics + high-granularity detectors
