A011100100004 AUTHOR (R.Guin,S.K.Das,S.K.Saha) A011100100005 REFERENCE (J,RCA,88,435,2000) A011100100006 INSTITUTE (3INDVEC) Radiochemistry Laboratory, BARC, Variable A011100100007 Energy Cyclotron Centre, Calcutta. A011100100008 FACILITY (ISOCY,3INDVEC) A011100100009 SAMPLE Targets of about 1 mg/cm**2 thickness were prepared by A011100100010 vacuum evaporation of natural rubidium chloride on A011100100011 7 mg/cm**2 aluminium backing. The target thickness was A011100100012 measured by weighting the foils before and after A011100100013 deposition of the target material. The target assembly A011100100014 consisted of a number of rubidium targets sandwiched A011100100015 between aluminium catcher and degrader foils. A011100100016 METHOD (STTA) A011100100017 (ACTIV) The duration of each irradiation was about A011100100018 3 hours and the beam current was around 300 nanoampere.A011100100019 (BCINT) Faraday cup.

A011100100036 COMMENT - By Authors - Natural rubidium contains about 27.8% A011100100037 Rb-87. At some bombarding energies the same product A011100100038 nucleus can therefore be formed from the two isotopes A011100100039 Rb-85 and Rb-87 by different reaction channels. To A011100100040 avoid any complication due to the presence Rb-87, the A011100100041 alpha-energy range for any particular reaction channel A011100100042 was selected in such a way that Rb-87 could not A011100100043 contribute significantly to the production of the A011100100044 nucleus of interest.
