******************************************************************
* 11-FEB-85: DATA EXTENDED DOWN TO 1.0E-5 EV AND UP TO 20 MEV
* AFTER CONSULTATION WITH H.GRUPPELAAR
* 6-MAR-85: Q-VALUES FOR MT=102,103,104,105,106,107 CORRECTED
* 28-SEP-87: RESONANCE PARAMETER SECTION UPDATED USING DATA *
* FROM THE 4TH ED. OF BNL-325, AND SPIN OF L=1 *
* RESONANCES HAVE BEEN RANDOMLY ASSIGNED BY THE *
