 TITLE=/ Excitation functions for (p,xn) and (p,pxn) reactions on
         natural 79+81Br, 85+87Rb, 127I and 133Cs upto Ep=52 MeV /;
 PURPOSE=/ To obtain systematic feautures of medium and low-energy
           nuclear reactions involving various combinations of
           particles and targets for producing isotopes of noble gases
           and their neighbour elements, and to deepen our knowledge of
           nuclear effects on natural abunbdances of noble gas isotopes
           as observed in meteorites and other celestial objects. /;

 /* Experimental Method:
    - Stacked target irradiation (10 min for short-lived products and
      1h for long-lived products. Energy degradation in the target
      stack was determined by the stopping-power computation code
      [K.Komura et al., J. Inorg. Nucl. Chem. 38(1976)2157].)
    - Beam current integrated (Proton beam was monitored by a 100%
      feedback-type current integrator, and the results from all the
      bombardments were found to be in agreement within 10% with those
      from 27Al(p,alpha+p+n)22Na measurements of the Al monitors.)
    - Gamma ray spectrometry
