Using data collected in the Belle experiment at the KEKB asymmetric-energy e+e
- collider we search for transitions ?(4S) ? ?b(1S)?, ?(5S) ? ?b(1S)? and ?(5S) ? ?b(2S)?. No significant signals are observed and we set 90% confidence level upper limits on the corresponding visible cross sections: 0.2 pb, 0.4 pb and 1.9 pb, respectively
